Applications of Zirconia Balls Bearing (ZBB)

Zirconia balls are mainly used as valve balls, fully ceramic bearings, force measurement balls, trackballs, fine mill balls, and can be used in such situations: high temperature, anti-corrosion, electric insulation, anti-magnet, non-lubrication, it's the ideal material for replacing steel balls under corrosive situation.

Product feature: Density can reach 6.05g/cm3

Product standard: 0.4mm~50.8mm(1/64"~2"), can provide other different kinds.

Provide grade: G3~G60

Notes

1. The color is white, if necessary, we can provide yellow ones.

2. We have mass stock, can deliver anytime you want.

3. Can meet the requirements of various non-standard sizes.

4. Coefficient of thermal expansion of zirconic is 10.5×106/℃, close to the coefficient of thermal expansion of metal, match up with metal but dimensional changes a lot under different temperature, so in some critical situations it's not as stable as silicon nitride.
