Advanced Fafnir ceramic hybrid ball bearings combine ceramic
rolling
elements
with
super
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.
