The XU080264 Crossed roller slewing bearings are widely used in requiring high levels of rotational accuracy, rigidity, and load-bearing capacity, where installation space is often limited，such as industrial robots (joints, rotary seats), CNC machine tools (rotary tables, turrets), medical equipment (CT scanners, surgical robots), precision measuring instruments, radar turntables, and aerospace applications.

The XU080264 bearing is a Crossed roller slewing ring bearing, without gear teeth, preloaded with an inner diameter of 215.9 mm , an outer diameter of 311 mm, a width of 25.4 mm. It typically uses P5, P6, P0 grade precision tolerances and 50Mn,42CrMo rings, GCr15 rolling mlement. It primarily bears high radial forces and moderate axial and tilting moment loads, Its dynamic radial rated load is approximately 56000 N, its static radial rated load is approximately 73000 N. Its dynamic axial rated load is approximately 79000 N, its static axial rated load is approximately 148000 N. sealed on both sides type, NBR (Nitrile Butadiene Rubber). together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.

The XU080264 Crossed roller slewing bearings mainly consist of an inner ring, an outer ring, cross-arranged cylindrical rollers, spacers, and a sealing device. The rollers are arranged at 90° intervals within the raceway, enabling a single-row structure to withstand multi-directional loads.

The cross-arrangement of the rollers in crossed roller slewing bearings allows them to simultaneously withstand radial loads, axial loads, and overturning moments. They exhibit extremely high rigidity and a precision grade of P5 or higher. Their compact structure and easy installation significantly save installation space.
