Crossed roller slewing ring

external-toothedsingle-rowfor public works, excavators and cranes

Cross-roller type slewing bearings, their rollers are arranged at 90° to each other at intervals between the inner ring and the outer ring. They can simultaneously bear loads from all directions (such as axial, radial, overturning moment, etc.). Because the rollers are in line contact with the track surface, the elastic deformation of the bearing under heavy load is correspondingly small and the rigidity is high. At the same time, it has mounting holes and sealing accessories or is equipped with teeth on the inner ring or outer ring to simplify the installation structure.
