This crossed roller bearing supports combined loads through a single row of rollers arranged at right angles to each other, giving high rigidity and accurate guidance under axial, radial and tilting moment loads simultaneously. The design height is 26.0 mm and the net mass is 11.925 kg. The bearing is sealed on both sides and supplied without gear teeth, so it functions as a slewing ring requiring an external drive arrangement. The cross arrangement of the rollers removes clearance between raceways and allows the ring to take load from any direction without a separate thrust bearing, which simplifies mounting and keeps the assembly compact for its height. Sealing on both faces keeps grease in place and restricts entry of dirt into the raceway, so the unit is suited to installations where the ring rotates slowly and the mounting structure must remain slim while still carrying moment loads reliably.
