ZrO2 6205ce Ceramic Ball Bearing
Product Overview: Model 6205
The 6205 is a high-performance, full-ceramic bearing designed for the most demanding applications. It features Zirconia (ZrO₂) for both the inner ring, outer ring, and balls, combined with a PTFE (Polytetrafluoroethylene) cage. This construction makes it an ideal solution for environments involving corrosion, extreme temperatures, electrical insulation, and where lubrication is impossible.

Full Ceramic Ball Bearings with P6/ABEC3-P4/ABEC7 Precision
Our ceramic bearings feature high temperature resistance, cold resistance, wear resistance, corrosion resistance, magnetic electrical insulation resistance, oilless self-lubrication, and high speed capabilities. These hi-tech products are designed for extreme environments and special conditions.
Materials & Properties
1.Rings & Balls: Zirconia (ZrO₂) Full Ceramic Construction:
- Provides complete electrical insulation and uniform resistance to corrosion and wear.
- Excellent Corrosion Resistance: Highly inert, resisting virtually all acids, alkalis, and organic solvents.
- Non-Magnetic & Electrically Insulating: Essential for sensitive electronic and medical equipment.
- High Hardness & Low Density: Offers excellent wear resistance and reduces centrifugal forces for smoother operation.
2.Cage: PTFE (Polytetrafluoroethylene)
- Superior Dry-Running Capability: The self-lubricating nature of PTFE allows for reliable operation with little to no lubrication.
- Extremely Low Friction: Ensures low starting and running torque.
- Outstanding Chemical Inertness: Resists a wider range of chemicals than most other polymers, matching well with the Zirconia's corrosion resistance.

Applications
This bearing is specifically chosen for applications where standard steel bearings would rapidly fail:
- Chemical & Process Industries: Pumps, mixers, and valves handling aggressive acids, alkalis, and solvents.
- Food, Beverage & Pharmaceutical: Equipment requiring frequent steam cleaning (CIP/SIP) and where lubricant contamination is prohibited.
- Electrical Insulation: Ideal for VFD-driven motors to prevent bearing fluting damage from stray currents.
- Semiconductor Manufacturing: Wafer processing equipment where metallic contamination and corrosion must be avoided.
- Precision Instruments & Laboratory Equipment: Used in MRI scanners, analytical instruments, and other applications requiring non-magnetic, corrosion-resistant, and low-torque components.
- High-Temperature & Vacuum Environments: Suitable for various ovens and vacuum chambers due to its low outgassing and thermal stability.
