Single Row Four Point Contact Ball Slewing Bearing (HS) Internal Gear for ship crane

5 0 Reviews

Slewing bearings are often made with gear teeth integral with the inner or outer race, used to drive the platform relative to the base.
As for other bearings that reciprocate, rather than rotating continuously, lubrication can be difficult. The oil wedge built up in a continuously rotating bearing is disrupted by the stop start motion of slewing. Instead, a hydrostatic bearing with pumped oil flow may be used.

Product Description

Single Row Four Point Contact Ball Slewing Bearing

(HS series) Internal Gear

The single row four point contact ball slewing rings is composed of two seat rings, which design in compact structure, steel ball contact with the circular raceway at four points; it can bear the axial force, radial force and the tilting moment at the same time.

It can be used for slewing conveyer, welding manipulator, light & medium duty crane, excavator, and other construction machinery.

Note:

1. N1 is the numbers of lubricating holes. Oil cup M10×1JB/T7940.1~JB/T7940.2

2. n-φ can change to tapped hole, tooth width can change to H-h.

3. The tangential tooth force in the form is the max tooth force; the nominal tangential tooth force is 1/2 of the max one.
