18CrNiMo7-6 34CrNiMo6 4140 carburizing Q+T treatment Splicing arc gear rack
Products:
Gear racks are utilized to convert rotating movement into linear motion. A gear rack has straight teeth cut into one surface of a square or round section of rod and operates with a pinion, which is a small cylindrical gear meshing with the gear rack.

We can supply many types of gear racks. If the application requires a long length requiring multiple gear racks in series, we have racks with the tooth forms correctly configured at the ends. These are described as gear racks with machined ends. When a gear rack is produced, the tooth cutting process and the heat treatment process can cause it to try & go out of true. We can control this with special presses remedial& processes.
