Advancements in Precision and Thermal Stability with Ceramic Sliding Bearings

Ceramic sliding bearings represent a significant leap in precision for high-speed rotation systems. Unlike traditional oil-lubricated bearings, which struggle with thermal stability due to the viscous nature of lubricants, ceramic bearings utilize water as a lubricant. This innovative approach enhances both thermal stability and precision.

• Wear Resistance: Perfect for boundary and dry friction applications with water lubrication, resistant to corrosion.
• Corrosion Resistance: Surpasses metal bearings in water lubrication, addressing common corrosion issues.
• High Rigidity: Minimizes mechanical vibrations, contributing to improved accuracy in high-speed applications.
• Longevity: Features high hardness, excellent compressive strength, and a low friction coefficient for an extended service life.
• Thermal Expansion: Adaptable to environments with significant temperature variations.

Lubricant Choice:

Switching from traditional mineral oils to water as a lubricant provides several advantages:

• Superior Thermal Management: Water’s higher specific heat capacity results in lower temperature increases during high-speed operation.
• Enhanced Safety: Water lacks a flash point and has natural extinguishing properties, making it a safer option compared to traditional lubricants.

Considerations for Engineers:

For engineers focused on the selection or development of precision spindles, ceramic sliding bearings offer a compelling solution. Their unique properties address the limitations of traditional metal bearings, making them an excellent choice for achieving high-speed and high-precision performance in advanced spindle technologies.
