Ceramic Bearings Advantages:

Ceramic bearings advantages are as below.

1. High speed and acceleration capability
Bearings can operate under the condition that the dn >3 million

2. Long life and wear resistance
The fatigue life of all-ceramic bearings is expected to be 10-50 times longer than that of chrome steel bearings.
At the same item, even the life of hybrid ceramic bearings(for example: HCB71904-C-T-P4S-UL) is about 3-5 times longer than that of chrome steel bearings.

3. Very little lubrication is required
The friction coefficient of ceramic materials is low which requires very little lubrication.

4. Anti-corrosion
Because the ceramic material is an inert material, which is more resistant to corrosion and wear.

5. High rigidity
Due to the high elastic modulus of ceramic materials, its rigidity is 15-20% larger than that of ordinary steel bearings.

6. High temperature resistance
All ceramic bearings can work at temperatures above 500 degree.

7. Low torque
According to the structure, the torque of the ceramic bearing is reduced by about 1/3.

8. Non-magnetic and non-conductive
All type of ceramic bearings can bear magnetism and electricity without damage.

Applications of Ceramic Bearing:

Ceramic bearings have the characteristics of high temperature resistance, cold resistance, wear resistance, corrosion resistance, high speed and so on.
Therefore, ceramic bearings can be widely used in aviation, aerospace, chemical, automotive, electronic equipment, metallurgy, electric power, textiles, pumps, medical equipments, etc


The rings and rolling elements of ceramic bearings are all-ceramic materials, which include
zirconia dioxide (ZrO2), silicon nitride (Si3N4), and silicon carbide (SiC).

Common cage materials include the below materials:
nylon 66
silicon nitride
stainless steel
