Product description：

Full ceramic bearing with diamagnetic electrically insulating, wear resistance and corrosion resistance, not self lubricating, high temperature resistance, cold and other characteristics, can be used in extremely harsh environment and special conditions.

Product features：

1.Hardly corroded, the ceramic rolling bearing is suitable for working under severe conditions filled with corrosive medium.

2.Due to electrical resistance, electrical insulation, can avoid arc damage bearings, can be used in a variety of insulation of power equipment.

3.Since the effect of thermal expansion and contraction of ceramics is smaller than that of steel, the bearing can be allowed to work in an environment where the temperature difference changes more severely.

4.Since the elastic modulus of ceramics is higher than that of steel, it is not easy to deform when subjected to stress. So it is advantageous to increase the working speed and achieve higher accuracy.

5.Because of no magnetic, it can reduce premature bearing flaking, big noise. Available in the demagnetization device, precision instruments and other fields.

Specification of 6806 30*42*7  high speed anti-corrision full ceramic ZrO2 ball bearing

Advantage of  6806 30*42*7  high speed anti-corrision full ceramic ZrO2 ball bearing

First, wear resistance, high hardness, low noise, high impact, easy-to-use to provide constant quality and long service life. Second, can increase the wound space, increase the torque, increase speed, increase the blade space and improve fan efficiency. Third, the high temperature, ≤1000 ℃ no distortion, no distortion, no lubrication running at high speed. Fourth, more suitable for working in harsh environments. Such as acids, alkaline environment, the oxidation environment. Five, density, non-magnetic, insulating and strong. Sixth, low thermal conductivity, low CTE, wear second only to diamond.
