Description

Lightweight and low moment of inertia. Low coefficient of thermal expansion, good dimensional stability in environments with large temperature changes, and the ability to maintain accuracy, Beneficial for maintaining the stability of equipment performance. Has good insulation performance Ceramic bearings are commonly used in high-speed machine tools, precision instruments, aerospace equipment, medical devices, etc Ceramic bearings are light, electrically insulating, and highly resistant to wear and abrasion. This makes them suitable for environments where normal
steel bearings fall short.
