Abstract of Sapphire Bearings
Sapphire bearing components are manufactured from high-purity single-crystal α-alumina (Al₂O₃), serving as critical elements in high-precision mechanical systems due to their exceptional physical properties. With a Mohs hardness of 9 (second only to diamond), these components significantly reduce friction and wear while extending equipment service life. Their chemical inertness resists most acid/base corrosion (except HF) without releasing contaminants in vacuum or high-purity environments, meeting stringent cleanliness requirements for semiconductor and medical applications. The thermal expansion coefficient (5.3×10⁻⁶/°C) closely matches steel, preventing thermal stress-induced failure. Additionally, their insulating properties (volume resistivity >10¹⁴Ω·cm) eliminate electrostatic interference, making them ideal for precision electronics. Advanced laser processing and ion beam polishing enable sub-micron dimensional accuracy (±0.5μm) and ultra-smooth surfaces (Ra≤0.01μm), delivering reliable performance for high-precision motion systems.
· Exceptional Hardness & Wear Resistance: Mohs 9 hardness with wear rates 1/10 of metal bearings
· Chemical Inertness: Resists strong acids (except HF), alkalis, and organic solvents with <0.001mm/year corrosion rate
· Thermal Stability: CTE of 5.3×10⁻⁶/°C (steel-compatible) prevents thermal stress failure
· Precision Machining Capability: Achieves surface roughness Ra≤0.01μm and flatness ±0.05mm/100mm
· Electrical Insulation: Volume resistivity >10¹⁴Ω·cm for anti-interference applications
1. Semiconductor Manufacturing Equipment
Critical for lithography wafer stages and vacuum robotic arms, their particle-free properties maintain chip yield with ≤0.1μm radial runout. In EUV lithography systems, sapphire bearings withstand intense UV radiation without degradation.
2. Medical Devices
Core components for dental handpieces (≥300,000 RPM turbines), offering ISO 13485-compliant biocompatibility and autoclave resistance (135°C cyclic sterilization). Miniature bearings (<1mm diameter) enable precise force feedback in surgical robots without MRI artifacts.
3. Precision Instruments
Used in AFM scanner heads and inertial guidance gyros, reducing motion noise to <0.1dB. Telescope equatorial mounts achieve 0.01-arcsecond tracking accuracy with sapphire bearings.
4. Industrial High-End Equipment
Fiber drawing capstans demonstrate <1μm wear after 1,000 operational hours, outperforming conventional ceramics. 5G antenna phase adjusters endure -40°C to 85°C thermal cycling.

1. Q: What material is jewel bearing?
A: Jewel bearings are typically made of synthetic sapphire (Al₂O₃) or ruby (Cr:Al₂O₃).
2. Q:What are the components of radial bearing?
A:The main components of a radial bearing include inner/outer rings, rolling elements (balls/rollers), and a cage (retainer).
