Rack and Pinion

Rack and Pinion

The Rack and Pinion mechanism is made up of two components. The rack, which is a long linear gear. And the Pinion which is a rotary gear. The rack and pinion convert rotary motion into linear motion. As the pinion rotates it moves either itself or the rack, this is dependent on which component is stationary.
