Wholesale Cross Roller Slewing Bearings

Slewing bearing product-1.2

Cross roller slewing bearings whose rollers are arranged 90° with each other at intervals between inner and outer rings. They can withstand loads from all directions simultaneously (such as axial, radial, overturning moment, etc.). Due to the linear contact between the roller and the track surface, the elastic deformation of the bearing under heavy load is correspondingly tiny, and the stiffness is relatively high. At the same time, it has mounting holes and sealing accessories, or the inner ring or outer ring is provided with teeth to simplify the installation structure.

Crossed Roller Bearings mainly consist of an outer ring, an inner ring, a plurality of rollers, and a plurality of spacers. The roller lies between the inner ring and the outer ring. The spacer is placed between rollers to prevent mutual friction between rollers to decrease the torque resistance for rotation.

In addition, the surface of the roller and the rolling track is linear contact. So, when the bearing is loaded, the loading area will be very large. Thus, the elastic deformation will be less, and the bearing will achieve a long service life. Each roller in Crossed Roller Bearing is crossed at a 90° angle, which can simultaneously bear the loading force from axial, radial, and the other direction.
