Rack and pinions are used for lifting mechanisms (vertical movement), horizontal movement, positioning mechanisms, stoppers and to permit the synchronous rotation of several shafts in general industrial machinery. On the other hand, they are also used in steering systems to change the direction of cars.Rack & Pinion imposes one kinematic constraint on the two connected axes: ω_P = R_RPv_R . The transmission ratio is: R_RP = 1 / r_P = ω_P / v_N = ± 2π / N_Pv_R
Also, it refers to the cylindrical gear that meshes with a rack in a rack-and-pinion mechanism which transforms rotational motion to linear motion.

Support rollers (yoke-type track rollers) are designed to run on all types of tracks and to be used in cam drives, conveyor systems, etc.. They are based on needle or cylindrical roller bearings.
