Ceramic Bearing 17*62*17mm Full ZrO2 with PTFE Cage
Specification
6403 6403-2RS Ceramic Bearing 17*62*17mm Full ZrO2 with PTFE Cage Anti-rust for bike and Corrosion resistant environment
Feature :Ceramic bearing with high temperature resistance, cold resistance, wear resistance, corrosion resistance, anti - magnetic insulation, no oil self - lubrication, high speed and other characteristics
Application: It can be widely used in the fields of aviation, aerospace, navigation, petroleum, chemical, automobile, electronic equipment, metallurgy, electric power, textile, pump, medical apparatus and instruments, scientific research and national defense, etc. It is a high-tech product for the application of new materials.
Ceramic bearing ring and rolling body using all ceramic materials, zirconia (ZrO2), silicon nitride (Si3N4), silicon carbide (Sic) three kinds.The retainer is made of polytetrafluoroethylene, nylon 66, polyether imide, zirconia, silicon nitride, stainless steel or special aviation aluminum to expand the application of ceramic bearing.
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.
Size Information
Ceramic material deep groove ball bearing is the most representative rolling bearing, a wide range of USES, can withstand radial load and two-way axial load.It is suitable for high speed rotation, low noise and vibration or high temperature, high temperature, corrosion, magnetic field, non-insulation and other fields that steel bearing cannot be used.
