Specifications:
Cage: PTFE
Material
Balls: ZrO2 Ceramic
Inner/outer races: ZrO2 Ceramic
Color: White

Features:
- 100% brand new and high quality .
- Deep groove full ceramic ball bearing.
- Because of the unique ceramic materials,
vacuum oil-free self-lubricating property,
in ultra-high vacuum environment,
zirconia ceramic bearings can overcome the plain bearing can not realize the problems of lubrication.
- With corrosion resistance, cold resistance, stress resistance to pressure,
small elastic, thermal conductivity, light weight,
the advantages of small friction coefficient.

1:The advantages of zirconia ceramic bearings: smooth rotation, corrosion resistance, no rust, oil-free self-lubricating, non-magnetic, insulation, high temperature.
2:Disadvantages: poor load capacity, installation and use of fragile, because of high accuracy, the bearing into the dust and impurities, will.
3:  We can provide China's best ceramic bearings, but because it is ceramic, does not apply to all occasions. If you have any questions, please contact me in time.
