Powered Drawer Actuator Calculator

How this powered drawer works

This arrangement is the horizontal version of a direct kitchen appliance lift. The actuator motor and body end are fixed to a rigid mount at the rear of the cabinet. The moving rod end pushes a rigid plate attached to the guided drawer. Because there is no lever or cable ratio, one inch of actuator stroke produces one inch of drawer travel.

The animation shows both a side cutaway and a top cutaway. In both views the actuator body remains fixed, the rod stays connected to the drawer push plate, and the drawer moves through the complete selected actuator stroke.

Measurements for a reliable result

• Drawer width, depth and height: measure the complete moving drawer, including its front panel where relevant.
• Required drawer extension: measure the horizontal movement from fully closed to fully open. The calculator selects the closest available full actuator stroke and uses that stroke as the animated drawer travel.
• Total loaded drawer weight: include the drawer, contents, front panel and all moving hardware. The slides must carry this vertical load.
• Measured opening resistance: use a pull scale to measure the highest horizontal force needed to start the fully loaded drawer moving. Measure through the travel and use the worst value.
• Rear installation space: after selecting an actuator, compare its fully retracted pin-to-pin length with the complete cabinet space available behind the drawer. Long-stroke actuators may require a deeper cabinet, a rear chase or an external rear mounting enclosure; this installation check does not reduce the requested drawer extension.

Actuator mounting and drawer guides

Mount the actuator so it is loaded only along its centerline. Use a rigid rear bracket for the motor/body end and a rigid push plate on the drawer for the rod end. The drawer slides—not the actuator—must resist drawer weight, twisting, racking and side load. Use guides on both sides and keep them parallel.

Check the fully closed and fully open positions with the exact actuator and brackets. Leave clearance for the motor housing, clevis rotation, wiring and the full extended rod. Add physical retention so the drawer cannot leave its guides.

Choosing an actuator

The family selector includes every suitable rod-actuator family in the catalogue. Super Duty actuators are shown first when their force and full stroke fit because they combine compact dimensions, quiet operation and high capacity; Industrial actuators take priority for unusually high force requirements.

If you already own an actuator family or stroke, select it and use Only use this model or Only use this stroke. The Fit actuator button then adjusts the selection only within those locked choices. The Actuator matches tab lists qualified variants, and Technical specs records the selected stroke, retracted and extended lengths, force demand and drawer dimensions.

Engineering limits

This calculator treats the measured opening resistance as the horizontal working load and applies 90% mechanical efficiency. It does not add acceleration, impact, misalignment, binding or cabinet deflection. Test the finished installation at maximum load, provide suitable end-of-travel control, and verify the actuator duty cycle, speed, controller and environmental rating before ordering.
