How to measure an electric linear actuator

Use the manufacturer’s dimensional drawing or measurements from a safely isolated assembly. For a pin-mounted unit, record retracted and extended lengths between the same pin centers. On a flange-mounted unit, use the mounting face and rod-end reference shown on the drawing. Include the rod-end thread or pin diameter.

Where to measure

Reference drawings. Verify dimensions on your part or the manufacturer’s drawing.

Stroke and installed lengths

Use the same mounting centers in both positions. Stroke is the extended length minus the retracted length. Confirm the usable stroke on the model drawing.

Motor flange and locating pilot

Measure the locating pilot across its center. On this four-hole flange, measure the bolt circle between opposite hole centers. Record the hole count and shaft or coupling dimensions separately.

What to include in a replacement quote

Send the complete actuator and motor models and note whether the motor is inline, parallel-mounted, or integrated. If you’re reusing the motor, include its pilot diameter, bolt pattern, shaft diameter and projection. Share the required load, speed, duty cycle, and any brake, feedback, or limit switch options.
