XZWD high precision single row ball slewing ring bearing without gear

Short Description:

Slewing Bearings, a kind of large bearing capable of carrying a combined load. Slewing bearings include four-point contact ball slewing bearings, double-row angular contact ball slewing bearings, crossed cylindrical (tapered) roller slewing bearings and three-row cylindrical roller bearings. There are four series for the slewing bearings. Four-point contact ball slewing bearings have higher static load capacity, crossed cylindrical roller slewing bearings have higher dynamic load capacity, crossed tapered ball slewing bearings have higher static load capacity, and crossed tapered ball slewing bearings have higher dynamic load capacity. The pre-infilling of roller slewing bearings enables the slewing bearings to have greater support rigidity and slewing bearing accuracy, and the three-row cylindrical roller combination slewing bearing has a higher load carrying capacity due to its high load capacity. The increase in the height of the lead to the slewing bearing, the various forces are borne by the different races, so that the same force, the diameter of the slewing bearing can be greatly It is a slewing bearing with high load carrying capacity and has a reduced size,thus making the main engine more compact.

About us

1.Point-contact rolling mode slewing bearing
The point contact rolling mode of operation is mainly used for four point contact ball slewing ringand crossed roller slewing ring.The working principle of the point contact radial and axial force combination to withstand the high quality requirements of the steel ball, and the track should be uniform angle.

2. Face-to-face rolling mode slewing bearing
Face contact rolling combined mode of work is mainly used for three rows of roller slewing bearing, it has the advantage of large contact surface, uniform bearing capacity and flexible rolling.

3. Face contact roller-slide combined mode slewing bearing
The face contact roller-slide combined working method is mainly used for rotary turntable bearings, and now the new rotary bearings are compact and highly accurate, so it is most suitable to use the face contact roller-slide combined working method.
