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

Slewing bearing surface treatment :
1.polishing treatment
2.galvanizing processing
3.phosphating treatment
4.Coating treatment

Generally, RKS.162.20.1904 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.162.20.1904 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.162.20.1904 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
