Rks. 061.20.0644 Slewing Bearing/Turntable Ring

Rks. 061.20.0644 Slewing Bearing/Turntable Ring
Product features:
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:
  1. Light series four-point contact ball slewing bearings 
  2. Medium size four-point contact ball slewing bearings
  3. Customized four-point contact ball slewing bearings
  RKS.061.20.0644 our point contact slewing bearing with external gear teeth
Advantage: RKS.061.20.0644  four point contact slewing bearing with external 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.

Four Point Contact Ball Slewing Bearing for Construction Machine

Slewing bearings are large-sized bearings which can accommodate a combined load, i.e., radial loads and tilting moment.
They are usually provided with holes for fixing bolts; internal, external or no gear; and lubrication holes and seals, which allow a compact and economical arrangement. In addition,
they often enable the elimination of many components necessary in the classical bearing arrangement.
It is composed of two seat rings. It has compact structure, light weight, and four-point contact between steel ball and arc raceway. It can bear axial force, radial force and overturning moment at the same time.
The construction machinery of rotary conveyor, welding manipulator, small and medium-sized crane and excavator can be selected.
Generally the slewing bearing have following types:
1. Single Row Four Point Contact Ball Slewing Bearings.
2. Single Row Crossed Roller Slewing Bearings
3. Double Row Ball Slewing Bearings
4. Three Row Roller Slewing Bearings
5. Thin Section Slewing bearings (Light type).
6. Thin Section Slewing Bearings (Flang
