1. DRE Longer Lifetime Antifriction Ball Bearing Full Ceramic Bearing :

High Temperature Antifriction Ball Bearing Full Ceramic Bearing are acclaimed by good quality,competitive price and good service.

The ceramic bearings can be made with ZrO2, Si3N4 and Al2O3 material.

The full ball bearings , deep groove ball bearings, angular contact ball bearings, self-aligning ball bearings and angular contact ball bearings can all be made into ceramic bearings.

2.  Longer Lifetime Antifriction Ball Bearing Full Ceramic Bearing advantages:

a.59% lighter than steel ball,which means less centrifugal force and less wear on the groove during high speed and acceleration.

b.44% larger elastic modulus,which means less deformation under load.

c.Harder with Rockwell hardness as 78.

d.Smaller friction coefficient.

e.Only 1/4 coefficient of thermal expansion of steel ,can endure sharp.

f.Superior surface finish can be achieved,Ra could be 4-6nm.

g.Can endure high temperature with high hardness and strength up to 1050 centigrade.

h.Never rust,and can roll without lurbrication.

i.More corrosion resistant than steel.

j.Free of matel contamination.

k.Non-magnatic and electric isolation.

 3. The properties comparison of all kinds of bearing:

4. Longer Lifetime Antifriction Ball Bearing Full Ceramic Bearing application:
