Product Description
Belparts excavator parts PC75UU-2 Slewing bearing 201-25-61100 Slew ring bearing for komatsu
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
