Stroke is the distance travelled by an actuator in motion. This is a measurement of the capability of a linear actuator. The stroke will help you determine whether the actuator will work in tandem with your application. The measurement of stroke is imperative to the efficient and safe combination and usage of the actuator and mechanism it is connected to. Stroke helps determine key factors such as the weight capacity of the actuator, how much time will it take, the speed of the motion, and the force that can be generated. When purchasing an actuator, it is important to know the measurement of stroke to understand its capabilities.
Detaching the Actuator
Disconnect the power supply to the application.
Detach the linear actuator from the mechanism.
Re-attaching the Actuator
Re-attach the actuator to the mechanism.
Switch on the power supply.
Measuring the Second Length
Let the application actuate to its full capacity. Ensure that the actuator produces its motion entirely.
Measure the length of the actuator in its extended state. Measure from the end of the actuator to the centre of the pin or bolt hole. Make sure that the exact spot of measurement is the same as the spot of your earlier measurement. Make a note of this length and call it "Length A".
