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 bearings 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 race-way contour.
The single row four-point contact ball slewing bearings is divided into three series:
- Light series four-point contact ball slewing bearings
- Medium size four-point contact ball slewing bearings
- Customized four-point contact ball slewing bearings
RKS.062.20.0544 four point contact slewing bearing with internal gear teeth
Advantage: RKS.062.20.0544 four point contact slewing bearing with internal gear teeth, it features compact in design, light in weight, high precision and small fitting clearance. As the rollers are 1:1cross arranged, it is suitable for high precision mounting and capable to bear axial force, resultant moment and considerable large radial force. The four point contact slewing bearing find widely application for transporting, engineering machines as well as for military products.
The three-row roller slewing bearing has three seat-rings,which separate the upper,lower and radial races,via which the load of each row of the rollers may be specified.It may bear different loads simultaneously and its load capacity is the largest one among the four models.

|Features||Slewing bearing is also called:Slewing ring bearing|
/Turnable bearing/Slewing ring etc.
Slewing Ring Bearings can accommodate axial,
radial and moment loads acting single
or in combination and in any direction.
They are not mounted in a housing or on a shaft,
but directly to a seating surface.
The inner and outer ring are supplied with mounting holes.
Both rings may have integral gears.
They are also referred to as slewing rings and tabletop bearings.
Slewing ring bearing can perform oscillating (slewing)
as well as rotating movements.
They may be used without gears or with internal or external gear
