Crossed Cylindrical Roller Bearings

1.Product Introduction: The cylindrical rollers are arranged in a 90° crossed pattern, capable of bearing compound loads, with a slewing accuracy reaching the level of 0.005mm, suitable for high-precision equipment.
2.Structure Type: The inner and outer rings can be integrated or split, with V-shaped raceways. The crossed rollers are equipped with brass or engineering plastic cages, and there is no seal (suitable for clean environments).
3.Size Range: Outer ring diameter: 50 - 1200mm, inner ring diameter: 30 - 1150mm, height: 10 - 70mm.
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: Semiconductor equipment (wafer transfer arms), precision robots (joint bearings), inspection instruments (high-precision turntables).
6.Key Inspection Items: Radial accuracy (≤0.005mm), parallelism of rollers, surface roughness of raceways.
