The S1810Y-RB-7P is a 120-diametral pitch, 20° pressure angle straight rack made of 416 stainless steel, 11 inches long, designed for linear motion in rack-and-pinion systems. It has a pitch diameter tolerance of +0.000/−0.001 inch, tooth-to-tooth spacing error of ±0.0005 inch, and total accumulated spacing error of ±0.002 inch. The parallelism of the pitch line to the base is held within ±0.001 inch. The rack measures 0.3467 inches in thickness and 0.3411 inches in width, with a pitch line height of 0.1067 inch and an overall width of 0.1247 inch.
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.
