Bearing Rings

Bearing rings in different forms: machined green rings before heat treatment, machined black rings after heat treatment, and ground rings ready for assembly. We use both through-hardened bearing steel that is commonly seen in China and carburized bearing steel such as SAE 8620H, 4118H and 3311, etc. from prominent steel sources in China, Japan, US, and Europe.
Size Range: OD from 30mm to 500mm
