The S1811Y-RC-3 is a 48 diametral pitch, 20° pressure angle gear rack made of 416 stainless steel, 9 inches in length, with four mounting holes of 0.147 inch diameter. It has a pitch line distance of 0.4592 inch, a face width of 0.230 inch, and a center distance tolerance of ±0.01 inch. Tooth-to-tooth spacing error is limited to ±0.0005 inch, total accumulated spacing error to ±0.002 inch, and parallelism of the pitch line to the base is controlled within ±0.001 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.
