Generally, RKS.162.16.1534 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.162.16.1424 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.162.16.1534 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

Bearing material:


Forging process:
The blanks of bearing rings are mainly made of rods and tubes, while the forging process is only applicable to rods. However, forgings are the most used blank materials in bearing manufacturing, and are suitable for large and medium-sized bearings. Forging can be divided into hot forging, cold forging and warm forging. Hot forging refers to processing above the re-crystallization temperature of the billet metal, warm forging is forging at a temperature not exceeding the re-crystallization temperature, and cold forging refers to forging at normal temperature.

The purpose of ferrule forging: 1. Through forging, obtain a blank with a size similar to the product, improve the utilization of metal materials, reduce the amount of machining, and reduce costs. 2. Forging can eliminate the internal defects of the metal, improve the structure, and thus increase the service life of the bearing.
General process of forging:
Bar material ,inspection, heating, blanking, secondary heating, forging, rolling,cooling, annealing, cleaning

Rough turning: Rough turning is performed according to the drawing of the turning process, and the cutting speed and cutting amount are strictly implemented according to the technical regulations (the general cutting speed is 5 rpm. The cutting amount is 10mm ~ 12mm).
2.2 Rough turning aging: After the rough turning of bearing parts is completed, three-point support and flat laying is not allowed (stacking is not allowed), and the precision turning processing can be performed after the aging time is not less than 48 hours.
2.3 Fine turning bearing parts When finishing turning, the cutting speed is 6 to 8 revolutions per minute, and the cutting amount is 0.3 to 0.5 mm.
2.4 Precision turning: In order to prevent the parts from deforming when the bearing parts are finally finished, the parts must be loosened to make the parts in a non-stressed state. The turning speed is 8 revolutions per minute and the cutting amount is 0.2 mm.
2.5 Cross and three-row roller slewing bearing inner ring special process: To prevent cross and three-row roller slewing bearing inner ring from deforming after heat treatment. The turning process must be performed in pairs, that is, the raceway is back-to-back processing. No cutting is performed before heat treatment, and cutting is performed after heating.
2.6 Finished car after heating: After the inner and outer rings of the bearing are heat-treated, the finished car turning process is carried out, and the technical procedures are the same as 2.3 and 2.43)
Heat treatment
3.1 Raceway surface quenching: The bearing raceway surface is quenched at medium frequency, the hardness is not less than 55HRC, the depth of the hardened layer is not less than 4mm, the width of the soft belt is less than 50mm, and the "S" mark is marked accordingly. (Sometimes customers can request carburizing, nitriding, carbonitriding, etc.)
3.2 Tempering after heat treatment: After the intermediate frequency quenching of the inner and outer rings of the bearing, it is required to be exposed to 200C degrees for 48 hours before being baked. To ensure that internal stresses disappear.
Rolling and milling processing—4.1 For turntable bearings with internal and external teeth, the grinding and milling teeth must be carried out before the grinding process, and they must be processed in strict accordance with the technological requirements, with an accuracy level of 8 or more.
5) Drilling—
5.1 Scribing: After measuring the external dimensions of the part, carry out the scribing and positioning procedures according to the dimensions specified in the drawing. The holes should not differ from each other by more than 3%.
5.2 Drilling: Check the scribe line size according to the drawing, and then perform the drilling process after ensuring that the dimensions are correct. The inner sleeve turntable bearing mounting holes should be combined and processed, and the error between the holes at 180C degrees between the soft belts should not be greater than 5%.
06) Grinding
6.1 Coarse grinding: Use medium corundum and soft three-grained granularity of 36 degrees and atmospheric hole resin grinding wheels for grinding. The line speed is controlled at 1500 rpm to prevent raceway burns. The maximum grinding depth must not exceed 1 mm.
6.2 Fine grinding: Use resin wheel grinding with a granularity of 46 degrees or 60 degrees, the grinding amount should be less than that of rough grinding, and the finish must reach the level specified in the drawing
