Generally, RKS.21 0841 slewing 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, a slewing bearing consists of an inner ring , an outer
ring and rolling elements−balls or cylindrical rollers−that 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 0841 Slewing 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
