1). RKS.21 0741 four point contact ball slewing bearing with an external gear has flange on inner ring, has the feature of light weight and stable rotation.

2). Generally, RKS.21 0741slewing bearings are large-size rolling bearings that can accommodate axial, radial and moment loads acting either singly or in combination and in any direction. They can perform both slewing (oscillating) movements as well as rotational movements.Basically, RKS.21 0741 slewing bearing consists of an inner ring , an outer ring and rolling elements balls or cylindrical rollersthat are separated by polyamide spacers .The rings, one of which usually incorporates a gear,are provided with holes to accommodate attachment bolts.The holes may be threaded.Generally, only the raceways in the rings are hardened and precision- ground. Integral seals made of acrylonitrile- butadiene rubber (NBR) keep the lubricant in, and contaminants out of the bearing.

RKS.21 0741Slewing bearings perform extremely well in a variety of applications such as:

• access platforms

• bucket wheel excavators

• conveyor booms

• cranes of all types

• small, medium and large excavators

• indexing tables

• ladle turrets

• offshore applications

• robots

• railway bogies

• rotary platforms

• stackers

• solar mirrors

• tunnel boring machines

• wind turbines
