Single row four-point contact ball slewing bearings are simple in design. They are particularly versatile and offer many advantages for applications where there are light-to medium axial, radial and moment loads.

 

Single row four-point contact ball slewing bearings are the most widely used slewing bearing type. NPB manufactures them in many executions and sizes.

 

Single row four point contact ball slewing bearings consist of a one-piece inner and outer ring and a set of spacers, protected by integral seals. The balls are inserted into the bearing via a hole in one of the two rings and are separated by polyamide spacers. After loading the ball set and spacers, the hole is closed with a plug that conforms to the raceway contour.

The NPB range of single row four-point contact ball slewing bearings is divided into three series:

light series four-point contact
