Key Property

Compared with steel balls, the main advantages of alumina balls are:

1. 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 conduction;
8. Electrical insulation.

Size and Grade:

 

Diameter specification: Ф 0.800mm~ Ф 100mm。

Available supply level: G10 ~ G100.

 

Application:

Al2O3 ball is anti-wear, heat-resistant, anti-oxidant, and corrosion resistant in salt solution and other chemicals. One feature of Al2O3 ball is its size remains unchanged up to 1100ºC. Al2O3 ball is mainly used for pump, valve and flow-meter.

 

Remarks: 1) plenty of stock. 2) non-standard size could be supplied. 3) fracture toughness is relatively lower. 4) Al2O3 ball is more suitable for cost reduction application. 5) Al2O3 ball is not suitable for application in HCl acid, HF acid and strong alkali.
