The four-point contact ball bearings are radial single row angular contact ball bearings featuring raceways that can handle axial loads acting in both directions. A limited radial load can be supported for a given axial load.
The Ring material is made of 42CrMo or 50 Mn steel, the ring and gear heat treatment is in accordance with ISO 281 and ISO 6336 standard.
Other parameters are made according to JB/T 2300-1999 and GB/T 699-1999.
