Bearing Jewels: The Unsung Heroes of Mechanical Precision
Bearing jewels are indispensable components in precision devices, minimizing friction and wear while ensuring smooth operation. Their exceptional hardness, low friction coefficients, and dimensional stability make them ideal for applications where accurate movement and longevity are paramount.
Benefits of Bearing Jewels
- Exceptional Hardness: Synthetic sapphires, with a Mohs hardness of 9, offer unmatched resistance to abrasion and wear.
- Low Friction: Ruby and spinel exhibit extremely low coefficients of friction, reducing energy loss and power consumption.
- Dimensional Stability: Bearing jewels maintain their precise dimensions over a wide temperature range, ensuring consistent performance.
- Corrosion Resistance: Inert materials like sapphire and ruby resist corrosion, extending the lifespan of mechanical systems.
How to Choose Bearing Jewels
- Material: Select diamond for extreme hardness and precision, or synthetic sapphire for a balance of properties.
- Size and Shape: Determine the appropriate dimensions and geometry based on the application requirements and available space.
- Surface Finish: Opt for a surface finish suitable for the mating surfaces, such as polished or lapped.
