The S1811Y-RC-4A is a 64 diametral pitch gear rack made from 2024-T4 aluminum with chromic acid anodizing, designed for linear motion applications. It has a pitch line distance of 0.4644 inches and a face width of 0.156 inches. The rack includes four mounting holes of 0.120 inches in diameter, spaced to match the 72, 80, 96, and 120 pitch models. Tooth-to-tooth spacing error is ±0.0005 inch, with a total accumulated spacing error of ±0.002 inch and parallelism of the pitch line to base held within ±0.001 inch. The rack is 7 inches in length and meets the 20° pressure angle standard.
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.
