The S1805Y-RA-5P is a round gear rack with a 72 diametral pitch and 20° pressure angle, made from 416 stainless steel. It has a pitch diameter of 0.1421 inch, a distance between teeth of 0.140 inch, a base thickness of 0.1872 inch, and an overall height of 0.156 inch. The rack features tooth-to-tooth spacing error of ±0.0005 inch and total accumulated spacing error of ±0.002 inch, with parallelism of pitch line to base held to ±0.001 inch. The pitch diameter tolerance is +0.000/-0.001 inch. The part is designed for precise linear motion applications in conjunction with a mating pinion.
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.
