Our company has specially purchased advanced surface induction quenching tool. The rolling track of the slewing bearing has been treated by quenching, and it can guarantee the hardness of HRC 55-62, and enough hardened layer depth can be treated by surface quenching according to user’s requirement. And hardness is at HRC55±5 and can guarantee enough depth.
Because it needs to transmit force, one of the rings of the slewing bearing is usually equipped with teeth. The heat treatment state of the gear is in generally normalizing or hardening and tempering state. According to application occasion, the gear can also be treated by full teeth quench or single-tooth quench. Single tooth induction quench can be divided into tooth surface tooth root quench and tooth surface quench.
