The main function of racks is to convert circular motion into linear motion. As a gear element, the rack is a toothed ring path of defined radius, which allows rotary motion to be converted into linear motion. There are applications where the rack is fixed while the pinion moves through and others where the pinion rotates on a fixed axis while the rack moves. The former is widely used in conveyor systems while the latter can be used in extrusion systems and lift/lower applications.
