Product Introduction: 6201 Full Zirconia Ceramic Bearing (with PTFE Cage)
Product Overview
The 6201 Full Zirconia Ceramic Bearing is a high-performance deep groove ball bearing manufactured to the international standard 6201 dimensions. It features inner ring, outer ring, and rolling elements made from high-purity Zirconia Ceramic, combined with a PTFE cage.
This unique material combination makes it the ultimate solution for extreme operating conditions involving corrosion, dry-running, high speeds, and electrical insulation, effectively solving the common failures of traditional steel bearings related to corrosion, electrical erosion, and lubricant contamination.
Material and Properties
1.Rings & Balls: High-Purity Zirconia Ceramic
- Exceptional Corrosion Resistance: Resists virtually all strong acids, alkalis, and organic solvents. Completely rust-proof.
- Electrical Insulator: Perfectly insulates against electric current, preventing electrical pitting (fluting) from VFD drives.
- Non-Magnetic: Generates no magnetic interference, ideal for precision instruments.
- Low Density & High Hardness: 45% lighter than steel, reducing centrifugal force for higher-speed capability. Offers excellent wear resistance.
- High Toughness: Superior impact resistance compared to most other engineering ceramics due to transformation toughening.
2.Cage: PTFE
- Superior Self-Lubrication: Possesses the lowest coefficient of friction of any solid material, enabling reliable operation under dry, unlubricated, or failed lubrication conditions.
- Excellent Chemical Resistance: Its corrosion resistance profile perfectly matches Zirconia, tolerating a wide range of chemicals.
- Non-Stick & High-Temperature Capability: Non-adhesive surface is easy to clean. Operates reliably from -200°C to +250°C.
Synergistic Effect: The combination of the PTFE cage with Zirconia balls results in very low friction and wear, outperforming metal-caged bearings significantly in dry or boundary lubrication states.
Working Principle
As a deep groove ball bearing, it supports shafts and reduces rotational friction via rolling contact. Its special materials introduce unique operational mechanisms:
- Creates an Inert Environment: The full ceramic construction forms an inert chamber inside the bearing, making it immune to chemical corrosion.
- Enables "Maintenance-Free" Operation: The self-lubricating nature of the PTFE cage allows for long-term, stable, low-torque operation where lubricants cannot be used or would cause contamination.
- Blocks Destructive Currents: As a perfect insulator, it severs the path for stray currents through the bearing, eliminating electrical pitting at its source and greatly extending service life in VFD motors.
- Handles High-Speed Operation: The low density of the ceramic balls significantly reduces centrifugal force at high speeds, minimizing friction heat and allowing for higher limiting speeds.
