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.
Can be ordered with or without seals.
Expanded options include custom preloads, 15° or 25° contact angles, and designs to ISO/ABMA 02, 10, 19 specifications.
High speed machining and grinding spindles
high speed mills
Pumps and compressors
Ceramic Bearing advantages:
a.59% lighter than steel ball,which means less centrifugal force and less wear on the groove during high speed and acceleration.
b.44% larger elastic modulus,which means less deformation under load.
c.Harder with Rockwell hardness as 78.
d.Smaller friction coefficient.
e.Only 1/4 coefficient of thermal expansion of steel ,can endure sharp.
f.Superior surface finish can be achieved,Ra could be 4-6nm.
g.Can endure high temperature with high hardness and strength up to 1050 centigrade.
h.Never rust,and can roll without lurbrication.
i.More corrosion resistant than steel.
j.Free of matel contamination.
k.Non-magnatic and electric isolation.
