How to manufacture high quality sealed spherical roller bearings

First step:the forging of sealed spherical roller bearings
 

The rings of sealed spherical roller bearings adopt forging technical process,forging can make the workpiece of metal distributed streamline.increasing material density of the rings of sealed spherical roller bearings,and the service life of sealed spherical roller bearings can be increased by 2 to 5times.

 

Second:lathe machine processing 

XRB(China bearing manufacturer) adopt CNC Lathe machine to process the ring of sealed spherical roller bearings,control the size and deformation of the ring strictly.Provide a good foundation for subsequent processing.

 

Third: heat treatment of sealed spherical roller bearings 

the quality level of heat treatment is very important for the quality of bearings,that is the technical gap 

with Japan and Germany quality,XRB have heat treatment equipment which are adopted advanced roller mesh belt type controlled atmosphere continuous production equipment, there are 5 temperature points when quenching and tempering,the temperature can be controlled precisely.its better for internal organizational structure of sealed spherical roller bearings ring,increased low cleaning technology when processing.reduce internal residual austenite of sealed spherical roller bearings ring,improve organizational stablity during storage and operation.

 

Fourth:Grinding process of sealed spherical roller bearings
 

1.all of XRB sealed spherical roller bearings are processed by high precision CNC grinding equipment,high precision machining,high degree of automation,high product consistency,and long service life.

2.Grinding production perform high control requirements of internal standards

3.Grinding process inspection including the first article inspection,process inspection and completion inspection.

 

Sealed spherical roller bearings can be used in heavy load application,XRB quality is the similar with Japan standard,but competitive price,welcome discuss for details.
