The S1811Y-RC-1A is a 24 diametral pitch, 20° pressure angle gear rack made from 2024-T4 aluminum with chromic acid anodizing, designed for linear motion applications. It has a pitch diameter of 0.4383 inches, a face width of 0.230 inches, and a center distance of 3.208 inches. The rack features four mounting holes with a diameter of 0.147 inches and meets tooth-to-tooth spacing tolerance of ±0.0005 inches and total accumulated spacing tolerance of ±0.002 inches. Parallelism of the pitch line to the base is held within ±0.001 inches.
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.
