Product Description

SD.650.20.00 is a light single-row four-point contact ball-type bearing.
This type of bearing is generally composed of two rings, with one or two of the rings having a flange structure. Internal or external tooth rings can be configured according to requirements. It has a compact structure, is lightweight, and is easy to install. The steel balls make four-point contact with the arc-shaped raceway, capable of simultaneously bearing axial force, radial force, and overturning moment.
It is suitable for lightweight and low-load mechanical equipment, vehicles, construction machinery rotating parts, etc. Based on the "650" in the model number, it is estimated that the inner diameter may be 650mm, but the specific
dimensions and other parameters should be referred to the sample or technical data of the relevant manufacturer. 
 

Slewing bearing Features: 
Slewing bearing has more features: compact structure, reliable guide, simple installation, and easily maintenance.
4.Slewing bearing application
Slewing bearings can be widely used in lifting transport machine, mining machine, construction machinery, port hoisting machinery, port oil transfer equipment, onshore and offshore crane, excavator, concrete machine, paper machine, plastic and rubber machine, weave machine, steel plant, electronic power plant, wind power generator, other construction and industry machines or equipments and other large rotary device.

                                                   LYDZC Bearing
               LYDZC was founded in 2012 which insists on product quality as the principle and implements the strategy of success through quality in the process of production. We focus on manufacturing high-precision bearings. 
Advanced quality idea
               Taking the science and technology as our guide 
               Creating international well-known brand as our goal
               We always provide the finest products,leading technology and excellent service to all of our customers at home and abroad to create a vast world through innovation and development.
              We take the world's top bearing brands as the example. 
              We try to keep our products perfect when we produce every single one.


                                      Strict production process


1.Rough grinding
Although it is a rough grinding process,  we still strictly control the size accuracy and geometric accuracy to lay a solid foundation for the precise grinding quality
Stable tempering
We have stable tempering on the ring after the rough grinding to eliminate stress and further stabilize the size and geometric precision
Thus guarantee high-quality products
2.Precision grinding
The use of advanced CNC automatic production ensure that the geometric accuracy of the product reach P4 or P2
Flaw detection
Every single crack of the spare parts must be detected thoroughly to guarantee Zero Defect
Demagnetization
The residual magnetism of bearing parts is eliminated to relieve the harm to the bearings and get high-quality product

3.Assembling
We use automatic assembling line with online inspection of vibration noise and clearance etc and classify the quality level strictly. All these measures guarantee delivery of qualified products to customers 
4.Spare parts
We choose steel ball ,cage ,dust cover , sealing ring , grease  ,and other parts in line with international standards to ensure our product quality
