Product List

The main advantages of zirconia balls are:

1. It is 23% lighter than the steel ball, reducing the centrifugal force, rolling and wear of the channel during high-speed and accelerated operation of the bearing;

2. Small friction coefficient and good rotational flexibility;

3. High temperature resistance, the service temperature can reach 750 ℃;

4. Never rust, can work without oil lubrication;

5. More resistant to chemical corrosion than steel;

6. No metal pollution;

7. Non magnetic;

8. Electrical insulation.


Ceramic ball size table

Purpose:

Zirconia ceramic ball is mainly used as valve ball, all ceramic bearing, measuring ball, track ball and fine grinding ball. It can be used in occasions such as high temperature, corrosion resistance, insulation, magnetic insulation and no lubrication. It is an ideal material to replace steel ball in corrosive occasions.

As a valve ball, zirconia ceramic ball has been successfully used in high-pressure homogenizer, diaphragm pump, metering pump, oilfield oil well pump, high-pressure spray gun and other equipment.

Company product features:

The density reaches 6.05g/cm3.

Product specification:

0.4mm ~ 50.8mm (1 / 64 "~ 2"), various gauge values can be provided.

Available supply levels:

G5~G40。

remarks:

1) Mainly white zirconia balls, and yellow zirconia balls can be provided if necessary.

2) A large amount of inventory is available to meet the requirements of delivery at any time.

3) It can meet the requirements of various non-standard sizes.

4) The coefficient of thermal expansion of zirconia is 10.5 × 10-6 / ℃, which is close to the thermal expansion coefficient of metal and fits well with metal, but the dimensional stability changes greatly with temperature. The contact failure form of rolling fatigue is destructive fragmentation, which is not as stable as silicon nitride material in some key occasions.
