A slewing ring consists of four core elements:

  1. 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.

  2. 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).

  3. Raceways

    • Precision-ground tracks for rolling elements.

    • Hardened surfaces resist brinelling and wear.

  4. Seals and Lubrication

    • Rubber or polyurethane seals prevent debris/water ingress.

    • Grease channels for automatic lubrication systems.
