Generally, RKS.22 0411 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.22 0411 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
Storage and storage life of slewing rings RKS.22.0411 :
Bearings should only be stored lying down, never standing up
The storage life of the bearings is limited by the storage life
of the grease. Experience shows that the greases with a mineral
oil base used can be stored for up to 3 years if the following
preconditions are met:
■ closed storage room
■ dry, clean rooms with temperatures between 0 ºC and +40 ºC
■ relative atmospheric humidity not more than 65%
■ no influence by chemical agents such as vapours, gases, fluids.
After long storage periods, the frictional torque may temporarily
be higher than that of freshly greased bearings. The lubricity of
the grease may also have deteriorated.
