Sealed spherical roller bearing Feature

1.Improved resistance to axial load of the sealed spherical roller bearings.
 

By optimized the internal shape,resistance to axial load performance increased 25% compared to the previous products,achieved apply to the high load area which are hard to use before,

 

2.sealed spherical roller bearings Improved allowable rotation speed
 

By stabilizing the rollers rotating state,reduce the bearing heat,to achieve the world's highest level of 

allowable rotation speed,improved 10% than before,this design meet the demand of machinery for high speed and high efficiency.

 

3.sealed spherical roller bearings can bear high temperature 200°C
thermal stabilization treatment as standard,it can be operating under high temperature 200°C.

 

4.High impact resistance of the sealed spherical roller bearings

High quality material and technical of heat treatment,make sure it can working under bad and dusty 

environment.

 

XRB(China bearing manufacturer) can produce complete series sealed spherical roller bearings,the quality ABEC-1,ABEC-3,ABEC-5 are avaiable,normal delivery time is 2-25days according to the designation and quantity,the most optimized solution always our target.

Main reason of the failure of spherical roller bearing for fan industry

The wrong installation of spherical roller bearings on the shaft,or different centre of the two bearings,
 

Small clearance cause there is no clearance after installation.

Bearing box severe vibration

Worse lubrication oil or dust or less filling

Bearing cover,housing connection bolts force is too large or too small.

Demagnetization is not clean or oil when bearing heating.

The surface of rollers or raceway of inner ring have hump burt.

 

XRB (China Bearing manufacturer) can supply the technical support for our customer who needed,not only the good quality spherical roller bearing,but also the professional technology consult.
