Classification of Slewing Bearings
Four-Point Contact Ball Slewing Bearings
Four-point contact ball slewing bearings feature a single-row ball design capable of supporting radial loads, axial loads, and tilting moments simultaneously. Their compact and lightweight structure provides a balanced combination of load capacity and cost efficiency, making them suitable for applications with space and cost constraints.
Eight-Point Contact Ball Slewing Bearings
Eight-point contact ball slewing bearings utilize a double-row ball design, enhancing load capacity and operational stability through multiple contact points. This structure allows for higher axial loads and tilting moments, ensuring smoother operation and making them ideal for heavy-duty applications requiring increased safety and reliability.
Crossed Roller Slewing Bearings
Crossed roller slewing bearings feature rollers arranged in a cross pattern, enabling them to support loads in all directions while providing high rigidity and rotational accuracy. Their stable contact and minimal deformation make them well suited for applications requiring high precision and stiffness.
Triple-Row Roller Slewing Bearings
Triple-row roller slewing bearings incorporate three rows of rollers to separately support radial loads, axial loads, and tilting moments, optimizing load distribution. This design offers exceptionally high load capacity and structural stability, making them ideal for large-scale and heavy-duty applications.
