The gear rack is a long, straight bar with teeth along its entire length. The teeth have the same pitch as the pinion gear which engages with it.

A gear rack and pinion is a type of linear actuator that comprise a pair of gears which convert rotational motion into linear motion. A circular gear called "the pinion" engages teeth on a linear "gear" bar called "the rack"; rotational motion applied to the pinion causes the rack to move, thereby translating the rotational motion of the pinion into the linear motion of the racks.
