Electric - Insulated Bearings / Ceramic Ball Bearing , 12000rpm - 75000rpm
nsk high quality, high precision and competitive price ceramic bearing 6304,6305,6306,6308
1, Material: ZrO2, Si3N4, SiC and Al2O3, etc.
1). High speed bearings:12000rpm--75000rpm
2). High temperature-resistant bearing:100°C--800°C.It can been applied in kiln,plastic,steel and other equipments that can bear high temperature
3). Corrosion-resistant bearings
4). Electric-insulated bearings
5). Vacuum bearings:self-lubricating without
Features:
Compared with traditional metal bearing, full ceramic bearing is featured in following aspects:
1. Could be used at higher temperature. Ceramic maintains mechanical properties at high temperature, so full ceramic bearing can be used at elevated temperature.
2. Corrosion resistant. Full ceramic bearing are more suitable for chemical industry application.
3. More suitable for temperature-variation application. Because thermal expansion co-efficiency of ceramic are smaller than metal, so the change of clearance of full ceramic bearing is smaller than that of metal bearing.
4. More resistance to seizing due to smaller thermal expansion.
5. Could work under poor lubrication, because ceramics are self-lubrication. Full ceramic bearing could be used at high-vacuum environment.
6. Could be used as insulation bearing and can prevent Electrical Arcing because ceramics is not electrical conductor.
7. Could be used in magnetic environment because ceramics do not respond to magnetic forces.
Application:
Full ceramic bearing could be used in following industries: chemical, semi-conductor, valve & pump, food, electronic, medical, vacuum, refining, insulation, etc.
Note:
Full ceramic bearing is not suitable for heavy loading, impact loading and variable loading application.
