Generally, RKS.061.25.1754  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, RKS.061.25.1754  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.

Single row four point contact ball slewing bearing.
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.

RKS.061.25.1754 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
