Design combines ceramic rolling elements with superfinished steel rings to run faster, cooler and longer.
Advanced design and materials help improve rigidity while reducing noise, vibration and operating temperature.

The lightweight ceramic balls have a superfine surface finish and high hardness that can help to extend service life up to 5 times that of standard steel bearings. Low friction characteristics enhance operation under minimal lubrication conditions and increase both life and speed capabilities of lubricants.

The ceramic’s greater modulus of elasticity significantly increases rigidity over steel bearings. Greater bearing rigidity improves spindle stiffness and accuracy for precise machining. Low thermal expansion helps maintain consistent bearing preload and stiffness at high speeds.
