VLU 200414 bearing performance:
  

VLU 200414 slewing bearing is composed of two seat rings. It has compact structure, light weight, and four-point contact between steel ball and arc raceway. It can bear axial force, radial force and overturning moment at the same time. The construction machinery of rotary conveyor, welding manipulator, small and medium-sized crane and excavator can be selected. The outer diameter:518mm,Inner diameter:304mm,Height:56mm, It is the light series bearing structure with internal teeth.

We have 70 employees, with 10 experienced engineers and professional technicists. The most of Engineer from LYC and ZWZ brand factory, they had owned produce and design and after sales experienced to design the bearing.We can also design the drawing according to the bearing work condition to meet the customer requirement.

Manufacturing ability:
Equipped with advanced manufacturing CNC Machine and test instruments to insure the accurate tolerance , all bearings are of uniform marking and packing with superior quality, reasonable prices and perfect services. Meanwhile we can make the module to test the mounting hole.
Quality control:
All the bearing from the forging to assembly process,It will need to inspect step.For the bearing forging we will need to test the size and hardness and surface, for the lathe process and grinding process,first it will need to check by the worker ,and then the professional inspector will checking the size and accurate,The last step the monitor will inspect the size. It can insure zero defect.

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)

Slewing bearings VLA 200844 N perform extremely well in a variety of applications such as:

• access platforms

• bucket wheel excavators

• conveyor booms
