Cross, three-row roller slewing Double Row Ball Slewing Bearing‍ bearing inner Special Process: To prevent cross, three-row thin section bearing inner heat treatment after deformation. When turning the pair must be processed, i.e., the raceway back-processing, cutting is not performed before the heat treatment, heat, cut molding.

6 heat treatment

Min raceway surface hardening (sometimes customer requirements can carburizing, nitriding, carbonitriding, etc.)

After quenching and tempering treatment

7 rolling, milling and Angular contact ball bearings‍ processing

8 during drilling according to customer requirements can be blue, phosphate, sulfide and other treatment

9 grinding coarse and fine grinding can be divided into two parts detection process 10.
