Slewing bearing rings are the core components of slewing bearings (turntable bearings), typically consisting of inner and outer rings. They support axial loads, radial loads and overturning moments. Manufactured by precision ring rolling or die forging, these rings feature a dense structure and continuous grain flow. After induction hardening of the raceway, they provide excellent contact fatigue strength and wear resistance. Widely used in cranes, excavators, wind turbines, solar tracking systems, robotic turntables and port machinery.
