3.Bearing heat treatment

Raceway heat treatment
The rotary-supported raceways are all subjected to surface induction quenching, and the quenching hardness ensures that in HRC55 ~ 62, the quenched layer can reach sufficient depth.
Gear heat treatment
Because of the transfer force, the slewing support is usually provided with teeth on one of the rings. Gear heat treatment state is normally normal or tempering state. The surface of the tooth can also be hardened according to the requirements of the user. The quenching hardness is HRC50 ~ 60 and sufficient depth can be guaranteed. According to different applications, gear quenching can be divided into full - tooth and single - tooth induction quenching. Single - tooth induction quenching can be divided into gear tooth root quenching and tooth surface quenching.
