1.we are the pioneer of ceramic bearing in China 2.material is ZrO2 3.full ceramic bearing 4.we are manufacturer

ZrO2:

Usage:high precision,vacuum, high temp,low temp,electric insulation,high precision ballscrew set,valve balls for acid,alkali,salt,measure pumps,flowmeter and valve ball plunger for deep well pump.

Characterisitic: resistance to strong acid,strong alkali,salt and gas of deleterious,long life,high hardness,especially resistance to wear,high modulus of elasticity
