Watch a screw-driven electric linear actuator from the inside. This original FIRGELLI 3D cutaway follows the motor, reduction gears, lead screw, drive nut, and output tube through one 21-second motion sequence.
Verified media record: 20.83 seconds, 1920 by 1080 pixels, H.264 MP4. The file contains no audio track and no spoken narration. The visual scene description below is provided instead of a speech transcript.
What the animation shows
Rotary input
The electric motor creates rotary motion. Its shaft drives the first gear in the reduction train.
Gear reduction
The gear train reduces motor speed and increases available torque before transmitting rotation to the lead screw.
Screw conversion
The rotating lead screw drives a constrained nut. Because the nut cannot rotate with the screw, it travels along the screw axis.
Linear output
The traveling nut moves the output tube to create push-pull linear motion. End limits, load, mounting, and control remain product-specific.
Scene-by-scene visual description
- 0:00-0:04A wide cutaway view establishes the complete actuator, with the motor and exposed reduction gears at one end and the long outer tube and output end along the motion axis.
- 0:04-0:08The camera moves closer to the drive end. The motor rotor, gear train, screw input, and the start of the lead screw become prominent.
- 0:08-0:12The view tracks along the lead screw and drive nut, showing the mechanical link between screw rotation and movement of the inner output assembly.
- 0:12-0:17The camera continues toward the output tube, keeping the screw, nut, guides, and surrounding housing aligned in one cutaway view.
- 0:17-0:21The animation returns to a wider transparent assembly view so the motor, gears, screw, moving tube, and mounting ends can be seen as one motion system.
Engineering scope and limitations
This animation explains component relationships in a representative screw-driven electric linear actuator. It is not a dimensional drawing, performance test, force or speed calculator, thermal model, service-life test, or installation instruction. Housing proportions, motion timing, gear geometry, materials, and internal details are illustrative. Use the current product page, data sheet, drawing, performance curve, and controller documentation for an actual design.

Frequently asked questions
Does this actuator animation have spoken narration?
No. The verified 20.83-second MP4 contains a video stream and no audio stream. The scene-by-scene visual description on this page describes what appears on screen.
What actuator components are visible?
The cutaway shows the electric motor, reduction gears, lead screw, traveling drive nut, output tube, housing, and mounting ends of a screw-driven electric linear actuator.
Does the animation show an actuator's exact speed or force?
No. It explains the motion path and component relationship. It is not a performance test, force calculation, speed curve, dimensional drawing, or product specification.
Can I reuse the FIRGELLI animation?
