The VLU 200544 Flange-type slewing bearings mainly consist of an inner or outer ring with a flange, another ring, rolling elements (steel balls or rollers), spacers, and sealing devices. The flange rings have mounting holes for direct bolt connection.
The flange structure of flange-type slewing bearings simplifies the installation process, eliminating the need for additional mounting seats, resulting in convenient assembly and precise positioning. They offer high overall rigidity, capable of simultaneously withstanding axial loads, radial loads, and overturning moments, while their compact structure saves space.
