HS Series Internal Gear Slewing Bearing
Single-row four-point contact ball slewing bearings consist of two raceways, featuring a compact structure and light weight. The steel balls make four-point contact with the arc-shaped raceways, enabling the bearing to simultaneously withstand axial loads, radial loads, and overturning moments. Rotary conveyors, welding positioners, small and medium-sized cranes, excavators, and other types of construction machinery are all suitable options.

Product Description

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 position 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.
