A slewing ring consists of four core elements:
Inner and Outer Rings
Forged from high-carbon chromium steel (e.g., 42CrMo4 or 50Mn) for durability.
Heat-treated to HRC 55-60 hardness.
Gear teeth may be machined onto the outer/inner ring for drive mechanisms.
Rolling Elements
Ball bearings: Used in lighter loads (common in mini excavators).
Roller bearings: Cylindrical or tapered rollers handle heavy axial/radial loads (e.g., large excavators).
Raceways
Precision-ground tracks for rolling elements.
Hardened surfaces resist brinelling and wear.
Seals and Lubrication
Rubber or polyurethane seals prevent debris/water ingress.
Grease channels for automatic lubrication systems.
