The S18C10MGAGE-G is a joining gauge for ground metric rack gears with a module of 1, a nominal tooth pitch of 15 mm, and a 20° pressure angle. It is made from AISI 1045 steel hardened to HRC 27…32, with ground teeth meeting ISO Class 5 accuracy. The gauge has a face width of 10 mm, a height of 15 mm, and an overall length of 43.6 mm. Its dimension tolerance is specified as -0.03 mm to -0.12 mm. The part is designed for use with S18C series racks, enabling precise alignment during rack pairing.
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.
