Excavator slewing bearing
Core Connecting & Rotating FunctionAs a key rotating joint, the slewing bearing connects the excavator’s upper structure (cab, engine) and lower structure (chassis, track), enabling smooth 360-degree rotation.
Strong Load-Bearing CapacityIt can simultaneously bear huge axial force, radial force and tilting moment, stably supporting the entire weight of the excavator’s upper structure.

Excavator Slewing Bearing: Advantages & Summary
Rational & Durable StructureComposed of inner ring, outer ring, rolling elements and cage, it has a scientific structure, ensuring stable operation and long service life.
Integrated Transmission DesignIts inner or outer ring is equipped with an integrated gear, which meshes with the drive pinion of the slewing reducer to convert power into rotational motion efficiently.
Effective Sealing ProtectionEquipped with special seals, it prevents sand, moisture from entering and lubricating grease from leaking, protecting internal components from damage.
Versatile Types for Different TonnagesThere are four types (single-row ball, double-row ball, crossed roller, three-row roller) to fit small, medium, large and extra-large excavators respectively.
High Rotation Precision & StabilityEspecially crossed roller and three-row roller types have excellent rigidity and high rotation precision, ensuring stable operation during heavy-load work.
Easy Maintenance & Fault PromptRegular lubrication and bolt inspection are simple; obvious fault signs (abnormal noise, shaking, metal debris) help timely maintenance and reduce losses.
Product Summary
The excavator slewing bearing (also called slewing ring or turntable bearing) is a key component connecting the upper and lower structures of the excavator. It supports the upper structure’s weight and enables 360-degree smooth rotation, with the ability to bear multiple loads. Composed of inner ring, outer ring, rolling elements and cage, it has integrated transmission and effective sealing protection. With four types suitable for different tonnages, it offers high rotation precision and stability. Easy to maintain and with clear fault prompts, it is an essential, reliable component for excavator efficient and safe operation in various working conditions.
