Zirconia Ceramic Bearing Rings: Core Components of High-Performance Bearings

Product Introduction

Zirconia ceramic bearing rings are precision bearing components made from yttria-stabilized zirconia (3Y-TZP) material, including inner rings, outer rings, and rolling elements. Manufactured through advanced powder metallurgy and precision machining technology, these products exhibit exceptional mechanical properties and special functional characteristics, making them an ideal choice for modern high-performance bearing systems.

Main Applications

• High-Speed Spindles: CNC machine tool electric spindles, precision grinding machine spindles, high-speed motor bearings

• Special Environments: Corrosion-resistant bearings, non-magnetic bearings, vacuum environment bearings

• High-Temperature Applications: High-temperature furnace bearings, heat treatment equipment bearings, aircraft engine bearings

• Precision Instruments: Medical equipment bearings, optical instrument bearings, measuring equipment bearings

• Semiconductor Equipment: Wafer transfer bearings, vacuum robotic arm bearings, clean environment bearings

Core Advantages

• Ultra-High Wear Resistance: Vickers hardness ≥1250 HV, wear resistance is 10-15 times that of bearing steel

• Excellent Corrosion Resistance: Resistant to acid and alkali corrosion, long service life

• Low Density: Density 6.05 g/cm³, reduces moving parts weight

• Non-Magnetic: Suitable for strong magnetic field environments

• Self-Lubricating: Low friction coefficient, can operate in oil-free environments

• High Precision: Machining accuracy up to P4 grade and above
