Advanced Fafnir ceramic hybrid ball bearings combine ceramic
finished
steel rings to run faster, cooler and longer in high-speed
machine tool spindles and other demanding
applications. The hybrid Fafnir ceramic ball bearings combination of materials provides superior
ceramic performance at a cost-effective price. super precision ceramic hybrid bearings deliver
outstanding service life and operating characteristics at high spindle speeds. The advanced design
and materials help improve rigidity while reducing noise, vibration and operating temperature.
Fafnir ceramic hybrid bearings help machine tool spindles achieve maximum accuracy at speeds
greater than 2 million DN
under air/oil lubrication, with reduced skidding, wear and heat generation.
Speeds greater than 1 million DN are
possible with grease lubrication. The lightweight silicon nitride
balls have a superfine surface finish and high hardness (Rc78)
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
Fafnir ceramics 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.
ABEC 9 ultra-precision geometry and micron-coded bores and outside diameters add to
superior system performance.Each bearing is 100% functionally tested per ABMA Standard
13. This assures consistent quality and smooth, low noise
operation.
