6201 Full Zirconia Ceramic Bearing with PTFE Cage 12mm Inner Diameter 32mm Outer

Product Specification

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.

Application Scenarios

This bearing is the ideal choice for the following high-end and demanding applications: 

• Chemical & Plating Equipment: Chemical pumps, metering pumps, plating barrels resistant to strong acids and alkalis.
• Food & Pharmaceutical Machinery: Filling machines, mixers, meeting hygiene requirements for lubricant-free operation and withstanding CIP/SIP cleaning.
• Variable Frequency Drive Motors: Serves as an insulating bearing to protect motor shafts from current erosion, improving reliability.
• Semiconductor Manufacturing: Wafer handling, vacuum applications, preventing metallic contamination and electrostatic effects.
•  Precision Instruments & Medical Devices: MRI scanners, analytical equipment requiring non-magnetic, low-friction, and corrosion-resistant components.
• High-Temperature & Vacuum Environments: High-temperature ovens, turbomolecular pumps.
