Product List

The main advantages of alumina balls are:

1. It is 50% 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 1750 ℃;

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:

Alumina ceramic balls are resistant to wear, heat, oxidation, water, salt solution and other chemical substances and acids. Another feature is the ability to maintain dimensional stability up to 1100 ℃. Alumina ceramic balls are not suitable for hydrochloric acid, hydrofluoric acid and strong alkali solutions. It is mainly used for pumps, valves and flow meters.

Product features: alumina content is 99.5%, and alumina balls with 99.8% content can be provided according to customer requirements.

Product specification: 1.588mm ~ 100mm.

Available supply levels:

G16~G60。

remarks:

1) There is a large inventory of alumina balls.

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

3) The toughness of alumina ball is relatively low.

4) Compared with silicon nitride ball, alumina ball is more suitable for low cost applications.
