Generally, RKS.162.14.1094 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.162.14.1094 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.
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.
