VLU201094-VSP Four Point Contact Slewing Ring Light Series 20, Without Gear Teeth
The VLU201094-VSP Flanged-type slewing bearings are widely used in Scenarios that require equipment weight, installation space, and rotational flexibility, but have medium or low load-bearing requirements, such as industrial robots (wrist joints), machine tools (tool magazines, turntables), automated equipment (robotic arms), medical equipment (surgical robots), packaging equipment, and aerospace (antenna drive mechanisms), among other fields.
The VLU201094-VSP bearing is a Four point contact bearing, slewing ring light series 20, without gear teeth with an inner diameter of 984 mm , an outer diameter of 1198 mm, a width of 56 mm. It typically uses P5, P6, P0 grade precision tolerances and 50Mn,42CrMo rings, GCr15 rolling mlement. It primarily bears axial, radial and tilting moment loads, Its dynamic radial rated load is approximately 179000 N, its static radial rated load is approximately 290000 N. Its dynamic axial rated load is approximately 198000 N, its static axial rated load is approximately 780000 N. sealed on both sides type, NBR (Nitrile Butadiene Rubber). together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
VLU201094-VSP bearings ( 984 mm x 1198 mm x 56 mm) have the advantages of Lightweight, compact, flexible in operation, with good load-bearing capacity, and easy to install, and are therefore widely used in the Industrial robots, medical equipment (CT scanner), packaging machinery.

The VLU201094-VSP 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.
