Regarding the problems of the slewing bearing teeth in the work, we have not received any complaints from customers in recent years, because our procedure technology of slewing bearing with internal gear and slewing bearing with external gear is very mature for the processing of teeth, especially the heat treatment of teeth.
The quenching of the teeth includes surface quenching, root tooth & surface quenching and full quenching.
The surface hardness of the quenched part is 50-60HRC, and the depth of the effective hardened layer must also meet the corresponding requirements according to the size of the teeth, and there should be no cracks on the surface of the tooth after hardening treatment.
We have been inspecting each set of products in strict accordance with the customer drawing requirements.
