WEBMar 6, 2023 · Rack and pinion gears are a type of mechanical component used for converting rotary motion into linear motion or vice versa. They consist of a straight bar, called the rack, with teeth on one side, and a steering gear, called the pinion, with teeth around its circumference. When the pinion rotates, all the teeth engage with the rack .
