RKS.061.20.0844 Slewing ball bearing with external teeth 772x950.4x56mm
We had offered the slewing bearing RKS.061.20.0844 to Europe customer that had used in waste management.Such as Compressors–Lowerers - Balers - Lifts - Transshipment stations - Washing systems ,Shaft systems etc. We had cooperated at least 3 years. Also the customer feedback the bearing performance very smooth working condition.
RKS.061.20.0844 Bearing belongs to medium size four point contact ball slewing bearing.The size 772x950.4x56mm. It consist of one outer ring with external teeth and inner ting and ball spare parts.

Most of Europe customer choose the C45N steel material,but in China market,we will use 50Mn or 42CrMo. The mechanical properties of 50Mn material better than your C45N, and the heat treatment performance better than C45N, So we advice that you can use 50Mn material.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.
Heat treatment process:
We had owned advanced quench and temper line heat treatment machine.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.)
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.
All the process will be inspected by professional inspectors. All the manufacture process will made by CNC machine control. The precision grade can reach to P5 P4 Grade.
The bearing package:
Inside packaging: plastic film + kraft paper + blue tape; Outside packaging: standard export free-fumigation wooden case.
