Product Description

Kitronik Linear Actuator

The Kitronik Linear Actuator converts the circular movement of a 180 degree servo (supplied) into motion in a straight line, one way and then the other. It can be mounted to a project to provide either horizontal or vertical movement.

Linear Actuators are useful for a whole host of different applications, like; robots, automated button switching, steering racks for buggies, a point switcher on a model railway, animating a diorama display, etc. Linear actuators are also used extensively in industry and in consumer products, such as; valves, cams, floppy disk drives and optical disk drives, just to name a few.

The Linear Actuator has been cut from a 5mm clear blue Perspex Sheet, the same material as used in our servo powered Klaw gripper. There are a range of mounting holes at either end of the rack including a 3mm hole, a 3mm square, and standard servo horn holes suitable for wire (1mm dia) and it has approximately 20mm of travel. It has a gear ratio of 2:3 and the stall torque of the provided servo is 1.5kg/cm at 6V and 1.3kg at 4.8V.
