A 1B12MY08A150 is a brass metric gear rack with a module of 0.8, a 20° pressure angle, and a length of 150 mm. It has a face width of 6.3 mm, a height of 12.7 mm, and a pitch of 11.9 mm. The rack has a length tolerance of ±3.8 mm. The part is designed for linear motion applications in conjunction with a pinion gear, and is part of a series with steel and nylon variants of similar mechanical dimensions.
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.
