Cross-roller slewing bearing (external gear type)
Single-row cross-roller slewing bearings consist of two raceways, featuring a compact structure, light weight, and minimal assembly clearance. They demand high installation accuracy. The rollers are arranged in a 1:1 crossed configuration, enabling the bearing to simultaneously withstand axial loads, overturning moments, and substantial radial forces. As a result, they are widely employed in lifting and conveying equipment, construction machinery, and military‑industrial applications.

Note
1, n1 is the number of lubricating oil holes. Oil cup M10x1JB/T7940.1~JB/T7940.
2 , according to the application, the user can specify the location of the oil hole, n-φ can be changed to threaded hole, thread diameter M, thread depth 2M
3. The internal gear circumferential force is the maximum circumferential force, and the rated circumferential force is 1/ 2.
4, "k" is the clipping coefficient.
5 the specifications in this sample are standard products., the inner and outer diameters are free tolerances. If the host and slewing bearing have coordination requirements, please in the contract or contract annex.( such as technical agreement) the fit size and accuracy are indicated in.
