That search ends today. The new C-Series Actuator represents our answer to the universal actuator challenge. With stroke lengths spanning 1 inch to 30 inches and force options from 45 to 225 lbs, this linear actuator eliminates the guesswork from specification selection. Whether you're automating a compact medical device or building a robust TV lift mechanism, the C-Series delivers the precise combination of reach and power your application requires.
Built from aerospace-grade aluminum alloy with IP54 ingress protection, the C-Series brings industrial-grade reliability to projects of every scale. This isn't just another actuator—it's the result of understanding what happens when engineers have access to truly adaptable motion control components.
Comprehensive Stroke Length Options: 1" to 30" Coverage
The stroke length of a linear actuator determines its maximum extension distance—the fundamental specification that defines what tasks an actuator can physically accomplish. The C-Series addresses the full spectrum of motion requirements with available stroke lengths at 1", 2", 4", 6", 8", 10", 12", 14", 16", 18", 20", 24", and 30 inches.
Short Stroke Applications (1" - 6")
Compact stroke lengths excel in applications where space is at a premium and movements are precise. The 1-inch and 2-inch options are ideal for control panel adjustments, camera positioning systems, and medical device components where millimeter-level precision matters. In automotive applications, these shorter strokes work perfectly for dashboard mechanisms, glove box automation, and custom gauge displays.
The 4-inch and 6-inch configurations bridge the gap between micro-adjustments and substantial movement. These lengths are commonly specified for adjustable monitor arms, ventilation louver control, and compact robotics projects. DIY enthusiasts frequently select these options for hidden compartment mechanisms and small-scale automation projects where concealment within furniture or cabinetry is essential.
Medium Stroke Applications (8" - 16")
This mid-range represents the sweet spot for many automation projects. An 8-inch to 12-inch stroke provides sufficient travel for standing desk height adjustments, cabinet door mechanisms, and marine hatch systems. These lengths deliver the extension needed for pop-up TV mechanisms in smaller cabinets while maintaining compact dimensions when retracted.
The 14-inch and 16-inch options support more substantial movements without requiring the mounting space of longer actuators. They're frequently specified for adjustable workbenches, tilting solar panel arrays, and agricultural equipment automation. In RV and marine applications, these stroke lengths are popular for bed lift mechanisms and adjustable seating platforms.
Long Stroke Applications (18" - 30")
Extended stroke lengths tackle applications requiring significant travel distance. The 18-inch to 24-inch range supports full-size TV lift installations, height-adjustable industrial workstations, and accessibility equipment like wheelchair lifts. These configurations provide the reach necessary for raising large displays from floor-level cabinets or creating substantial height adjustment in standing desks.
The 30-inch maximum stroke opens possibilities for heavy-duty applications: large equipment covers, industrial door automation, and architectural elements requiring extensive movement. This extended reach makes the C-Series competitive with industrial actuators while maintaining the compact form factor and straightforward installation that defines our product philosophy.
Precision-Matched Force Ratings: 45 lbs to 225 lbs
Force rating - the maximum load an actuator can push or pull—determines what an actuator can actually move. Specify too little force, and your mechanism stalls under load. Specify too much, and you're paying for capacity you'll never use while dealing with a larger, heavier actuator than necessary. The C-Series offers force options at 45, 90, 150, and 225 lbs, providing the right balance for virtually any application.
Light-Duty Force (45 lbs - 90 lbs)
The 45 lb configuration handles lightweight mechanisms with precision and efficiency. This force rating is optimal for actuating ventilation panels, lightweight display adjustments, and small cabinet doors. The lower current draw of these units makes them ideal for battery-powered applications and solar installations where power efficiency is critical.
At 90 lbs, you gain capability for standard cabinet doors, medium-weight display screens, and most DIY furniture automation projects. This force level manages the typical resistance encountered in drawer slide mechanisms and pop-up shelf installations while maintaining the speed advantage of lower-force actuators.
Medium-Duty Force (150 lbs)
The 150 lb option represents the workhorse specification for general automation. This force rating handles most TV lift applications, adjustable desk mechanisms, and medium-weight access doors. It provides sufficient capacity to overcome the friction and binding that occurs in real-world installations—the resistance that theoretical calculations often underestimate.
In automotive and marine environments, 150 lbs manages tonneau cover mechanisms, equipment hatches, and storage compartment lids. The force margin ensures reliable operation even as mechanical components wear or when dirt and debris increase friction over time.
Heavy-Duty Force (225 lbs)
The 225 lb maximum force tackles demanding applications where substantial loads must be moved reliably. This rating supports heavy equipment covers, large-format TV installations, industrial door automation, and machinery positioning systems. The additional force capacity proves essential in applications with mechanical disadvantage—situations where mounting geometry creates less-than-ideal force application angles.
This force level also provides the safety margin required in accessibility equipment and human-supporting applications, where reliable operation under maximum load isn't just preferred—it's mandatory. When combined with longer stroke lengths, the 225 lb option brings C-Series capabilities into territory traditionally served only by dedicated industrial actuators.
Technical Specifications and Design Features
The C-Series architecture reflects decades of field experience in linear motion systems. The actuator body is machined from aluminum alloy, providing the strength-to-weight ratio necessary for reliable operation without the bulk of steel construction. This material choice delivers corrosion resistance in marine and outdoor applications while maintaining thermal stability across operating temperature ranges.
Motor and Gearbox Assembly
The C-Series employs a 12V DC motor driving a precision leadscrew through a planetary gearbox. This configuration provides smooth, consistent motion across the full stroke length while minimizing backlash—the slight play that occurs when reversing direction. The motor assembly operates within a sealed housing, protecting internal components from dust and moisture ingress to IP54 standards.
Power consumption varies with force rating and load, but typical current draw ranges from 2-6 amps under normal operating conditions. This moderate power requirement allows the C-Series to integrate with standard power supplies and control boxes without requiring specialized electrical infrastructure.
Integrated Limit Switch System
Internal limit switches automatically stop the actuator at full extension and full retraction, preventing mechanical damage from over-travel. These switches are factory-set and require no field adjustment, simplifying installation and eliminating a common source of setup errors. The limit switch circuit interrupts power to the motor, providing fail-safe protection even if control system timing is imperfect.
This built-in protection is particularly valuable in DIY installations where control systems may lack sophisticated position feedback. Users can confidently command full extension or retraction without monitoring position—the actuator automatically stops at the correct endpoints.
Mounting and Connection Hardware
Both ends of the C-Series feature clevis-style mounting points that accommodate standard mounting brackets. This universal interface allows the actuator to connect to existing hardware or custom fabricated brackets using readily available fasteners. The mounting holes accept 6mm bolts, providing secure attachment while maintaining ease of assembly and disassembly for maintenance or adjustment.
Electrical connection is achieved through a standard two-wire interface for non-feedback models. Simply reverse polarity to reverse direction—the elegant simplicity that makes linear actuators accessible to makers without electrical engineering backgrounds. The wire leads are protected by flexible conduit, preventing wire damage during actuator movement.
Real-World Applications Across Industries
The true measure of a universal actuator is its appearance in diverse applications—from weekend hobbyist projects to production machinery. The C-Series has already found its way into applications we anticipated and several we didn't, demonstrating the creative solutions engineers develop when specifications aren't constraining design.
Home and Office Automation
In residential applications, the C-Series powers hidden TV mechanisms that raise displays from cabinets or foot-of-bed furniture. The quiet operation and smooth motion eliminate the mechanical clatter that characterizes cheaper actuators. Adjustable standing desks benefit from the medium-stroke, medium-force configurations, providing ergonomic height adjustment without the complexity of multi-motor systems.
Custom cabinetry installations use C-Series actuators for motorized spice racks, adjustable shelving, and concealed storage compartments. Home theater enthusiasts employ them for projection screen deployment, speaker positioning, and equipment rack ventilation systems. The actuator's compact footprint allows it to hide within furniture dimensions, maintaining the clean aesthetics that separate custom automation from obvious mechanical systems.
Automotive and Marine Applications
Custom vehicle builders integrate C-Series actuators into trunk lid automation, tonneau cover mechanisms, and custom dashboard elements. The corrosion-resistant construction withstands the temperature extremes and moisture exposure inherent in automotive environments. In classic car restorations, these actuators enable modern convenience features while maintaining period-correct exterior appearance.
Marine applications present particularly demanding conditions—salt spray, constant vibration, and limited access for maintenance. The C-Series IP54 rating provides adequate protection for cabin installations, while the aluminum construction resists the galvanic corrosion that destroys steel components in marine environments. Boat builders specify these actuators for berth adjustments, hatch automation, and convertible seating mechanisms.
Industrial and Commercial Installations
While not replacing dedicated industrial actuators in heavy production machinery, the C-Series serves admirably in light industrial applications. Equipment covers, material handling positioning systems, and automated quality control fixtures benefit from the combination of reliable operation and straightforward integration. The competitive price point makes automation economically viable for lower-volume production equipment where expensive industrial components can't be justified.
Retail display automation represents an emerging application category. Motorized product displays, adjustable signage, and dynamic window installations all benefit from the C-Series's quiet operation and precise positioning. Commercial furniture manufacturers integrate these actuators into height-adjustable conference tables, ergonomic workstations, and accessibility-compliant serving counters.
Medical and Accessibility Equipment
The medical and accessibility sectors demand reliability above all else—equipment must function correctly every time, without exception. The C-Series's integrated limit switches and fail-safe design philosophy align with these requirements. Adjustable examination tables, patient positioning equipment, and therapeutic devices all employ linear actuators for precise, repeatable positioning.
Accessibility equipment builders use C-Series actuators in wheelchair lift tables, adjustable countertops, and reach-assist devices. The smooth motion eliminates the jarring movements that can cause discomfort or injury, while the consistent force output ensures reliable operation regardless of load variation within the rated capacity.
Specification Selection: Choosing the Right Configuration
Selecting the optimal C-Series configuration requires understanding three fundamental parameters: required stroke length, necessary force, and duty cycle. Most applications involve straightforward calculations, but several common scenarios deserve specific guidance.
Determining Required Stroke Length
Required stroke equals the total distance your mechanism must travel, plus a margin for mounting geometry. If you're lifting a TV 24 inches from a cabinet, don't specify a 24-inch stroke—you'll need additional length to account for the mounting points not being perfectly aligned with the TV's vertical travel. As a general rule, add 10-20% to your calculated travel distance to accommodate mounting geometry and provide operational margin.
Consider the actuator's retracted length as well. A 30-inch stroke actuator in its fully retracted state still occupies significant space. Ensure your installation volume accommodates the actuator throughout its full range of motion, including any additional clearance needed for mounting brackets and connection hardware.
Calculating Necessary Force
Force requirements depend on the weight being moved and the mechanical advantage of your mounting geometry. For vertical lifting applications, the required force equals the weight of the load divided by the number of actuators. However, friction in slide rails, binding in mechanisms, and angular mounting positions all increase the necessary force beyond simple weight calculations.
A practical approach: calculate the theoretical force requirement, then multiply by 1.5 to 2.0 to account for real-world inefficiencies. If calculations suggest 80 lbs of force, specify the 150 lb actuator. This margin ensures reliable operation and extends actuator service life by preventing continuous operation at maximum capacity. Under-specifying force is the most common cause of actuator failure in DIY installations.
Understanding Duty Cycle
Duty cycle refers to the percentage of time an actuator operates versus rests. The C-Series is rated for a 20% duty cycle—it can operate for 2 minutes out of every 10 minutes without overheating. This specification is more than adequate for most automation applications, which involve brief movement periods followed by long static holds.
A TV lift that extends for 30 seconds, remains extended for hours, then retracts for 30 seconds operates well within duty cycle limits. However, applications requiring continuous reciprocating motion may exceed the thermal capacity of the motor and gearbox. If your application involves near-constant movement, consult the duty cycle specifications carefully or consider implementing cooling periods in your control programming.
Installation Best Practices and Common Mistakes
Proper installation determines whether an actuator delivers years of reliable service or fails prematurely. Most actuator failures result not from component defects but from installation errors that create unnecessary stress on mechanical components.
Critical Importance of Alignment
Linear actuators must operate in a straight line. Any side loading—force applied perpendicular to the axis of motion—rapidly wears internal components and can cause premature failure. Use mounting brackets that allow slight angular movement, accommodating any minor misalignment as the mechanism moves through its travel range.
The clevis mounting points provide rotational freedom specifically to prevent side loading. Never rigidly mount both ends of an actuator—at least one end must be able to pivot. If your application requires rigidity, consider pairing the actuator with slide rails or linear bearings that guide the load and prevent lateral forces from reaching the actuator.
Electrical Connection Guidelines
The C-Series operates on 12V DC, with polarity determining direction of travel. Connect positive to the red wire and negative to black for extension; reverse polarity for retraction. This simple control method works with basic switches, relays, or dedicated control boxes for more sophisticated operation.
When installing multiple actuators in synchronized applications, ensure they receive identical voltage to maintain synchronized movement. Voltage drop in long wire runs can cause actuators to operate at different speeds, resulting in binding and mechanical stress. Use appropriately sized wire for your current requirements—14 AWG for runs up to 25 feet is typically adequate for single actuator installations.
Common Installation Errors to Avoid
Securing the actuator rigidly at both ends creates internal stress as the mechanism moves. Always allow pivoting at mounting points. Insufficient force specification leads to stalling under load—when in doubt, specify the next higher force rating. Ignoring friction in slide mechanisms and guides results in under-powered installations that struggle or fail completely.
Operating actuators beyond their duty cycle causes motor overheating and premature wear. If your application requires frequent cycling, implement cooling periods or consider industrial actuators designed for continuous duty. Finally, neglecting to account for the actuator's retracted length in space planning leads to clearance problems that only become apparent during installation.
Integration with Control Systems and Automation Platforms
The C-Series's straightforward electrical interface makes it compatible with virtually any control system, from simple toggle switches to sophisticated programmable controllers. This flexibility allows the actuator to integrate into existing automation ecosystems without requiring specialized interface hardware.
Basic Switch Control
The simplest control method employs a DPDT (double-pole, double-throw) switch to reverse polarity and control direction. This approach requires no programming and works reliably for applications where manual control is acceptable. Add a power supply and a switch, and you have a complete control system.
For wireless control, our remote control kits provide RF-based operation with range up to 100 feet. These systems include a receiver module that handles polarity switching and a handheld transmitter—ideal for applications where running control wires would be impractical.
Arduino and Microcontroller Integration
Makers using Arduino or similar microcontroller platforms can control the C-Series through relay modules or motor controller boards. The built-in limit switches eliminate the need for external position feedback in many applications—simply command extension or retraction and let the internal switches stop movement at the endpoints.
For applications requiring precise position control, consider our feedback actuator variants that include potentiometric position sensing. These versions provide analog voltage output proportional to actuator extension, enabling closed-loop control and precise positioning anywhere within the stroke range.
PLC and Industrial Control Systems
Industrial installations using PLCs (Programmable Logic Controllers) can interface with the C-Series through relay outputs or motor control modules. The actuator's 12V DC operation integrates with standard industrial control voltage levels, though an appropriate power supply may be necessary to convert from 24V industrial standard to 12V actuator voltage.
The integrated limit switches provide feedback to the control system, allowing PLC logic to confirm full extension or retraction before proceeding with subsequent process steps. This simple feedback mechanism often proves sufficient for industrial applications where precise mid-stroke positioning isn't required.
Maintenance Requirements and Troubleshooting
Linear actuators require minimal maintenance when properly installed and operated within specifications. However, understanding basic maintenance procedures and common issues helps ensure long-term reliability and quick resolution of problems when they occur.
Routine Maintenance Procedures
The C-Series's sealed construction protects internal components, but external elements benefit from periodic inspection. Check mounting bolts for tightness—vibration can loosen fasteners over time. Inspect the actuator shaft for damage, scoring, or contamination. While the shaft is plated for corrosion resistance, cleaning dirt and debris prevents abrasive particles from entering the seal.
Verify electrical connections remain secure and free from corrosion. In marine or outdoor installations, apply dielectric grease to electrical terminals to prevent moisture intrusion. Listen for unusual sounds during operation—grinding or binding noises indicate misalignment or internal wear requiring attention before failure occurs.
Common Issues and Solutions
If an actuator fails to move, first verify power supply output voltage and polarity. Use a multimeter to confirm 12V DC at the actuator terminals during attempted operation. Check for blown fuses or tripped breakers in the power supply circuit. If voltage is present but the actuator doesn't move, excessive load may have triggered thermal overload protection—allow cooling time and verify force specifications are adequate for the load.
Slow or jerky movement typically indicates insufficient power supply capacity. Confirm your power supply can deliver adequate current for the installed actuator. Undersized power supplies cause voltage sag under load, resulting in poor performance. Binding or resistance in the mechanism being actuated also causes labored movement—verify the load moves freely when manually operated with power disconnected.
If an actuator operates in only one direction, suspect limit switch issues or control system problems. Test with direct battery connection and polarity reversal to isolate whether the fault lies in the actuator or control system. Limit switches can fail in the triggered position if subjected to excessive shock loads or if internal adjustment has shifted—this typically requires actuator replacement or factory service.
C-Series Comparison with Other Actuator Types
Understanding how the C-Series compares to other actuator categories helps identify when it's the optimal choice and when alternative solutions might better serve specific requirements.
Versus Micro Linear Actuators
Our micro linear actuators offer more compact dimensions and lighter weight, making them ideal for space-constrained applications with minimal force requirements. However, they typically provide lower force output and shorter stroke lengths than the C-Series. Choose micro actuators for electronics enclosures, small robotics, and precision positioning where size matters more than force. Select the C-Series when you need more substantial force or stroke length.
Versus Track Actuators
Track actuators include integrated guide rails that prevent side loading and provide superior linear guidance. This built-in rail system makes them ideal for heavy loads requiring precise straight-line motion. However, they're bulkier and more expensive than the C-Series. Choose track actuators when load guidance is critical and space permits. Select the C-Series for installations where separate slide rails provide guidance or where the load naturally constrains movement to a single axis.
Versus Industrial Actuators
Dedicated industrial actuators offer higher force ratings, continuous duty operation, and enhanced environmental protection. They're engineered for demanding production environments where failure isn't acceptable. However, they're significantly more expensive and often require more complex control systems. Choose industrial actuators for high-duty-cycle applications and harsh environments. Select the C-Series for intermittent-duty applications where industrial-grade specifications aren't necessary and cost efficiency matters.
Pricing and Value Proposition

Frequently Asked Questions
How do I determine which force rating I need for my application?
Calculate the theoretical force required by dividing the weight of your load by the number of actuators, then multiply by 1.5 to 2.0 to account for friction, binding, and mechanical inefficiency. For vertical lifting of 100 lbs with one actuator, you'd need 100 × 1.5 = 150 lbs minimum force rating. If your mounting geometry creates angular force application (common in lever-type mechanisms), increase this safety margin to 2.0 or consult mechanical advantage calculations for your specific geometry. When in doubt, specify the next higher force rating—under-specifying force is the most common cause of actuator performance problems.
Can I synchronize multiple C-Series actuators for applications like lift tables?
Yes, multiple C-Series actuators can be synchronized by powering them from the same power supply and control system. For optimal synchronization, ensure all actuators receive identical voltage by using appropriately sized wiring and maintaining equal wire lengths to each actuator. Minor speed variations between units are normal due to manufacturing tolerances—for applications requiring precise synchronization, consider our feedback actuator versions that enable closed-loop control where a controller monitors position and adjusts speed to maintain alignment. For most applications like lift tables and platforms, powering matched actuators in parallel provides adequate synchronization.
Is the C-Series suitable for outdoor installations?
The C-Series carries an IP54 ingress protection rating, meaning it's protected against dust and water splashing from any direction. This makes it suitable for covered outdoor installations and marine cabin environments, but not for direct weather exposure or submersion. For installations exposed to rain, snow, or continuous moisture, construct a protective housing or select an actuator with higher IP rating. The aluminum construction resists corrosion better than steel alternatives, but electrical connections should be protected with dielectric grease and weatherproof enclosures in outdoor applications.
What is the operating speed of the C-Series actuator?
Operating speed varies based on force rating and load, but typical extension/retraction speed ranges from 0.5 to 1.5 inches per second. Higher force actuators generally operate slower due to gearing ratios—the 225 lb force model extends more slowly than the 45 lb version. Actual speed under load may be slower than no-load speed, particularly when operating near maximum force capacity. For applications requiring specific timing (like synchronized multi-actuator systems), test with your
