The S181YYM0808200 is a metric gear rack made of 304 stainless steel with a module of 0.8, a pitch of 7.2 mm, a length of 138 mm, a height of 13.4 mm, a width of 5 mm, and a 20° pressure angle. It is designed for linear motion applications in conjunction with a pinion gear. The part has an ISO class 9 rating and is machined to an h7 tolerance on the pitch diameter.
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.
