The S1807Y-RA-4P is a 64 pitch, 20° pressure angle precision rack made of 416 stainless steel with a round profile. It has a pitch diameter of 0.2044 inches, an overall length of 0.1992 inches, a thickness of 0.156 inches, and a bore diameter of 0.2497 inches. The tooth-to-tooth spacing error is ±0.0005 inches and the total accumulated spacing error is ±0.002 inches. The parallelism of the pitch line to the base is held to ±0.001 inches. All dimensional tolerances are specified as direct limits.
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.
