The S18C05M128P0812G is a metric gear rack with a module of 0.5, 128 mm usable face width, 8 mm pitch, and 20° pressure angle, designed for linear motion applications. It is made from AISI 1045 steel hardened to HRC 27-32, with ground teeth conforming to ISO Class 5 tolerance. The rack has an h8 tolerance of 0/-0.022 mm for its 8 mm pitch dimension and a total length of 201.06 mm. Machined ends allow for joining with other racks. The part is compatible with joining gauges for module 0.5 racks.
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.
