Product Description
Belparts excavator parts SH120-3 Slew bear JCB130 Slew ring bearing
Excavator slewing rings are precision-engineered components requiring proactive maintenance. Understanding their design, failure modes, and repair protocols ensures operational longevity and minimizes downtime in construction and mining applications.
The slewing ring (also known as a slewing bearing or turntable bearing) is a critical component in excavators, enabling 360-degree rotation between the upper structure (house) and the undercarriage. It supports axial, radial, and moment loads while ensuring smooth movement for digging, lifting, and material handling operations.
1.1 Key Functions
-
Facilitates full rotation of the excavator’s upper structure.
-
Distributes dynamic and static loads from the boom, arm, and bucket.
-
Ensures stability during operation.
-
Transmits hydraulic and electrical signals between upper/lower sections (in advanced models).
1.2 Applications
-
Hydraulic excavators (mini to large mining models).
-
Crawler cranes.
-
Wind turbine yaw systems.
-
Other heavy rotating machinery.
