CS205 Ceramic Bearings(ZrO2 rings+ZrO2 balls+PEEK cage+ PTFE seals), with HIP ZrO2 material
Full Zirconia Ceramic Bearing with PTFE Cage and double PTFE seals, available in P6 and P5 precision grades.
Product Overview
The CS205 Full Zirconia Ceramic Bearing is a high-performance deep groove ball bearing manufactured to international standard dimensions. It features inner ring, outer ring, and rolling elements made from high-purity Zirconia Ceramic, combined with a PEEK cage, and PTFE SEALS.
This unique material combination provides the ultimate solution for extreme operating conditions involving corrosion, dry-running, high speeds, and electrical insulation, effectively solving common failures of traditional steel bearings related to corrosion, electrical erosion, and lubricant contamination.
Material and Properties
Rings & Balls: High-Purity Zirconia Ceramic
Exceptional corrosion resistance: Resists virtually all strong acids, alkalis, and organic solvents
Electrical insulator: Prevents electrical pitting from VFD drives
Non-magnetic: Ideal for precision instruments
Low density & high hardness: 45% lighter than steel with excellent wear resistance
High toughness: Superior impact resistance due to transformation toughening
Cage: PEEK
Superior self-lubrication with the lowest coefficient of friction
Excellent chemical resistance matching Zirconia
Non-stick surface with high-temperature capability (-200°C to +250°C)
The combination of 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 immune to chemical corrosion
Enables maintenance-free operation with self-lubricating PTFE cage
Precision instruments & medical devices: Non-magnetic, low-friction components
High-temperature & vacuum environments: Reliable performance in extreme conditions
