Zirconia ceramic ball bearing (ZCB)
Definition: Zirconia ceramic ball bearing is also known as zirconia hybrid bearing, the rolling element is zirconia ceramic ball, inner ring and outer ring is metal. The structure is the same as metal bearings
Material: kinds of ferrule: bearing steel, stainless steel. Kinds of ceramic balls: zirconia.
Precision：P0~P4
Size range: minimum inner diameter 3mm, maximum outer diameter **0mm
Model: All series and models of ball bearings
We
provide more than ***0 different models, including all kinds of
metric and imperial deep groove ball bearings,self-aligning ball
bearings, angular contact bearings, surface bearings, insert
bearings. And we also provide open ,seal ring, dust cover
structure.
According
to the working condition of customers, we can design and
manufacture non-standard bearings.
Holder: NYLON, PTFE, PEEK, stainless steal, copper or crowded ball
Advantages:
1
Higher limit speed: zirconia is lighter than steel which means
less centrifugal force, so it will higher the limit speed in the
same precision.
2
High-precision situations: ceramics hardness and young modulus is
both higher than steel, less mechanical deformation under the
same load, so it can used in High-precision
situations.
3
The service life is longer, 5 times than steel bearings: ceramic
is lighter to have less high-precision situations and less roller
path load , and because of the friction coefficient is smaller
than steel, the operate temperature is lower to reduce the
attrition, extend the service life of roller path.
4
Insulation: zirconia are non-conducting, therefore they can be
used for insulative situations.
5
Poor lubrication or unlubricated situations: A) the contamination
between silicon nitride and steel will not occur under poor
lubricated situations. This means its service life is much longer
when ceramics hybrid bearings operate under bad dynamic
lubrication.B) Silicon nitride balls can resist corrosion, even
thought the corrosion happened in ferrule, bearings can still
operate for a certain time.
Application area: high-speed motorized spindle bearings, machine tool spindle bearings, engine bit bearings, high speed spindle bearings, and bearings in HDD , roller skate , fishing gear, model airplane,battery-operated toys.
