Cross Roller Slewing Bearing

1.Product Introduction: With a crossed roller design, it can bear bidirectional axial loads, radial loads and overturning moments. The slewing accuracy reaches the level of 0.01mm, suitable for precision slewing scenarios. 2.Structure Type: It has an annular structure. The inner and outer rings have double raceways, with crossed cylindrical rollers, equipped with nylon cages to prevent collisions. Some models are equipped with dust-proof seals and reserved with evenly distributed mounting holes. 3.Size Range: Outer ring diameter: 80 - 2000mm, inner ring diameter: 60 - 1850mm, height: 10 - 80mm. 4.Material: Inner ring / outer ring: 50Mn, 42CrMo; rolling elements: GCr15 bearing steel, GCr15SiMn (optional for impact resistance); seals: nitrile rubber, fluororubber (optional for oil and high temperature resistance). 5.Application Fields: Precision machine tools, robot joints, radar antennas, inspection equipment, semiconductor manufacturing equipment. 6.Key Inspection Items: Radial runout, precision of roller arrangement.
