2C Series Ceramic Bearings
This application is Seawater-related Equipment, Plating Machine, Electronic Device, Equipment used in Low Temperature, Etching Equipment, etc.
Features
Corrosion Resistance
Usable in extremely corrosive environment, by using ceramics for outer and inner rings and balls, and fluorine resin for retainer.
Nonmagnetism
Completely nonmagnetic, by using ceramics.
No-lubricant
Usable without grease, even in environment where greases can not be used, by using fluorine resin for retainer.

＊Allowable radial load and rotation are figures when using the bearings without lubricants.
Precautions
- Ceramics are extremely brittle to impact of dropping and others. Please handle with care.
- Fitting is class H tolerance range.
