There are two main types:
Uses steel balls as rolling elements.
Best for small to medium excavators (lower load capacity).
Advantages: Smoother rotation, lower cost.
Disadvantages: Less durable under extreme loads.
Uses cylindrical or tapered rollers.
Designed for large excavators and heavy-duty applications.
Advantages: Higher load capacity, longer lifespan.
Disadvantages: Slightly less smooth rotation.
Small excavators (1-20 tons): Usually ball-type.
Large excavators (20+ tons): Typically roller-type.
Rings: High-carbon chromium steel (e.g., 42CrMo, 50Mn).
Rolling Elements: Hardened alloy steel.
Gear Teeth: Induction-hardened for wear resistance.
Forging – Shaping steel into rings.
Machining – Precision cutting of raceways and gear teeth.
Heat Treatment – Hardening for durability.
Grinding & Assembly – Smoothing surfaces and adding seals.
