The S18CCPM020P100G is a ground rack with a circular pitch of 2 mm, 20 teeth, and a usable face width of 100 mm, designed for linear motion in rack-and-pinion systems. It is made from AISI 1045 steel hardened to HRC 27-32, with ground teeth at a 20° pressure angle and h8 tolerance on the mounting dimensions. The rack has machined ends for joining and a height of 12 mm, pitch diameter of 11.364 mm, and overall length of 200 mm. It meets ISO Class 5 precision standards.
A gear rack is used to create linear motion out of rotary motion. Gear racks have square or round shafts with straight, equally spaced teeth; a pinion gear’s teeth mesh with the teeth of the rack. We combined as a unit they are referred to as a “rack and pinion”.
Gear racks are used in a variety of applications, and it may be necessary to pair them for length. Pairing can be accomplished by having racks with matching machined ends. They can also be modified to contain mounting holes. Racks and pinions are found in lifting and positioning systems where vertical or horizontal linear movement is necessary. They are commonly found in steering systems for vehicles, lathes, packaging machines, depth and height gauges, elevators, gates, stair lifts, and pneumatic actuators, to name a few.
Our inch and metric gear racks are available in steel, stainless steel, aluminum, nylon, and plastic in a variety of finishes and heat treatments, in pitches ranging from 120 to 1/20 and modules from 0.3 to 10.
