Key Features
- High temperature and cold resistance
- Excellent wear and corrosion resistance
- Magnetic and electrical insulation properties
- Oilless self-lubrication capability
- High-speed operation suitability
Materials & Properties
Rings & Balls: Zirconia (ZrO₂) Full Ceramic Construction
- Complete electrical insulation and uniform resistance to corrosion and wear
- Highly inert, resisting virtually all acids, alkalis, and organic solvents
- Non-magnetic and electrically insulating - essential for sensitive equipment
- High hardness with low density for excellent wear resistance and smooth operation
Cage: PTFE (Polytetrafluoroethylene)
- Superior dry-running capability with self-lubricating properties
- Extremely low friction ensures low starting and running torque
- Outstanding chemical inertness matching 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 chemicals
- Food, Beverage & Pharmaceutical: Equipment requiring frequent steam cleaning where lubricant contamination is prohibited
- Electrical Insulation: VFD-driven motors to prevent bearing fluting from stray currents
- Semiconductor Manufacturing: Wafer processing equipment avoiding metallic contamination
- Precision Instruments: MRI scanners, analytical instruments requiring non-magnetic components
- High-Temperature & Vacuum Environments: Ovens and vacuum chambers due to thermal stability
Our Manufacturing Advantages
- Professional Team: 40+ years of experience since 1982 with eleven invention patents and dedicated R&D
- Advanced Production: Fully automated grinding and assembly line producing 3 million sets annually
- Material Mastery: Vertical integration from raw materials to finished products for consistent quality
