China Origin source zirconia (ZrO2) ceramic bearing 608 Xingruida sliding plate bearing rolling bearing customization manufacturers-Xingruida

Shenzhen Xingruida Bearing Co., Ltd

In the aspect of structural ceramics, zirconia ceramics are widely used in the field of structural ceramics because of its high toughness, high bending strength, high wear resistance, excellent thermal insulation performance and thermal expansion coefficient close to that of steel.

Zirconia ceramic bearing is a kind of industrial ceramics, which is made by selecting the appropriate ultra-fine nano zirconia ceramic powder, hot pressing and sintering at a certain temperature. The best mechanical properties and wear resistance were obtained. The bending strength, fracture toughness and Vickers hardness of zirconia ceramics are 95.3 MPa, 9.1 MPa M1 / 2 and 12.7 GPA, respectively.

1、 Disadvantages of zirconia ceramic bearings

At present, zirconia ceramic bearings in domestic CPU radiators stainless steel shaft and copper shaft sleeve have the following disadvantages:

Disadvantages of zirconia ceramic bearing:

(1) Zirconia ceramic bearing is not wear-resistant and cannot be lubricated in use;

(2) Zirconia ceramic bearing CPU radiator mostly runs at high speed, so it is generally noisy, easy to heat, easy to cause the fan burned.

2、 Zirconia ceramic bearings have the following advantages

Zirconia ceramic bearings have the following advantages:

(1) Zirconia ceramic bearing is wear-resistant, high hardness, low noise, impact resistant, easy to provide constant quality and long service life. (2) Zirconia ceramic bearing can increase the winding space, torque, speed and blade space, and improve the fan efficiency. (3) Zirconia ceramic bearing has high temperature resistance, no deformation and distortion when the temperature is less than or equal to 1000 ℃, and no oil lubrication when running at high speed.

(4) Zirconia ceramic bearing is more suitable for working in harsh environment. Such as acid, alkaline environment, oxidation environment, etc.

(5) Zirconia ceramic bearing has low density, non-magnetic and strong insulation.

(6) Zirconia ceramic bearing has low heat conduction, low CTE and wear resistance only inferior to diamond.

(7) It can be used in extremely harsh environment and special working conditions.
