The VLI200944-N-RL1 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 VLI200944-N-RL1 bearing is a Four point contact bearing, slewing ring light series 20, internal gear teeth with an inner diameter of 840 mm , an outer diameter of 1048 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 170000 N, its static radial rated load is approximately 250000 N. Its dynamic axial rated load is approximately 188000 N, its static axial rated load is approximately 670000 N. lip seals on both sides type, NBR (Nitrile Butadiene Rubber). together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.

The VLI200944-N-RL1 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.
