Crossed Roller Bearing Slewing Bearing With Rotor And Stator For Textile Machinery OD 590mm

We had developed crossed roller bearing slewing bearing for textile machinery. The bearing raceway is crossed structure. The bearing will be fixed two shafts.The shaft diameter is 85mm. It is very higher strictly precision grade

 Textile Machinery OD 590mm reference actual picture as following:

Slewing bearing is one of our main products.
1. four point contact ball slewing bearing (no gear, external gear, internal gear);
2. two row ball slewing bearing (no gear, external gear, internal gear);
3. crossed cylindrical roller slewing bearing;(no gear, external gear, internal gear);
4. three row cylindrical roller slewing bearing;(no gear, external gear, internal gear);
5. crossed tapered roller slewing bearing; (no gear, external gear, internal gear);
6. ball and roller combined slewing bearing.(no gear, external gear, internal gear);

Bearing Parts
Steel ball/Roller:carbon-chromium bearing steel GCr15SiMn or GCr15 for rolling Material
Cage: include integral cage, segment cage and spacer-type cage. We use 20# steel or copper for integral and segment cages, PA 1010 resin or QA110-3-105 albronze for spacer-type cages.
Seals:uses NBR or VITON, few felted wool.

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

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
• solar mirrors
• tunnel boring machines
• wind turbines
