The cost is high, and teeth are usually manufactured on one of the collars of the slewing bearing due to the requirement of transmitting force during processing. The heat-treated state of the gear is generally a normalized or quenched and tempered state. The tooth surface can be quenched according to the requirements of users, the quenching hardness is between HRC50 and 60, enough depth can be ensured, the roller path of the slewing bearing is subjected to surface induction quenching treatment, the quenching hardness is between HRC55 and 62, enough quenching layer depth can be achieved, and the processing requirement is high, so that the cost is increased. The slewing bearing rolling body adopts carbon-chromium bearing steel which is hardened integrally; the slewing bearing ring is made of surface hardening steel, and when no special requirement is required by a user, 50Mn steel is generally selected for manufacturing. The slewing bearing rolling bodies are made of carbon-chromium bearing steel which is hardened integrally. Manufactured by GCr15 or GCr15SiMn steel; the slewing bearing ferrule adopts surface hardening steel, and when no special requirement is required by a user, 50Mn steel is generally selected for manufacturing, so that the cost is high.
