Rack and Pinions


Racks in any length and up to 12 mod pitch and Face width 150mm

Rack and pinions gears are used to convert rotation into linear motion or linear motion into rotation. The rack gear is the flat toothed part and the pinion is the gear. The diameter of the gear determines the speed that the rack gear moves as the pinion turns.

A perfect example of rack gears and pinion gears system is the steering system on many cars. The driver turns the steering wheel which rotates the gear which then engages the rack so as the gear turns it slides the rack to the right or the left depending on which way the steering wheel is turned.
