Ceramic Bearings

PYC bearing is a specialized manufacturer of various ceramic bearings.
They are basically two types of ceramic bearings.
Full ceramic bearings:
Full ceramic(All-ceramic) bearing of ZrO2 material
Full ceramic bearing have excellence performance as special electrical and magnetism
resistance, wear and corrosion resistance, lubrication and maintenance free when
working, especially high and low- temperature application. Etc. Could be used in
awful environment and specially condition. The rings and balls made by full ceramic
material: ZrO2, as a standard constructor, the cage made by PTFE, generally
we also can make the cage with GFRPA66-25, PEEK, PI, AISI, US304, SUS316, Cu, etc
Full ceramic(All-ceramic) bearing of Si3N4 material
Full ceramic bearing made with Si3N4 have some better performance than ZrO2, the
rings and balls made by full ceramic material: Si3N4, as a standard constructor,
the cage made by PTFE, generally we also could make the cage with GFRPA66-25, PEEK, PI, Phenolic Textolite Tube, etc. Compares than the material of ZrO2, The SiN4 ceramics bearings could endure heavier load and can be used in higher temperature
environment. Also we could offer precision ceramic bearing which generally used
in high-speed and high-rigidity spindle. The manufactured clearance can P4 TO UP
grade.
Full ceramic (all-ceramic) bearing of full complement balls:
Full ceramic bearing of full complement balls has an add-ball gap on its side.
Because using no frame design, the bearing able to install more ceramic balls than
the standard construction, so the heavier load ability increased more. In addition,
to avoid the limited of the frame material, this bearing same as the full ceramic
bearing of ceramic cage has corrosion resistance and high temperature application.
This series of bearing is not for high-speed choice, it should be to install on
the unforced side.
Full ceramic (all-ceramic) bearing of ceramic cage:
Ceramic cage has excellence performance as wear and corrosion resistance, high strength,
lubrication and maintenance free when working. Adopting the ceramic cage,
ceramic bearing can be used in the most inclemency environments as corrosive, low
temperature, high vacuum. The normal used ceramic materials are ZrO2, Si3N4 or
SIC.
Hybrid ceramic bearings:
Typical hybrid bearings consist of steel raceways, a retainer, a lubricant and ceramic
balls. With bearing rings made of bearing steel (AISI52100) or stainless steel (AISI440C).
The ceramic ball bearing is mainly made of silicon nitride(Si3N4), zirconia (ZrO2)
or alumina (Al2O3), among which Si3N4 is of excellent overall performance and
haS become the preferred material for ceramic ball bearing. Hybrid bearings can
achieve higher speeds, greater accuracies, and have a longer service life than steel
bearings which is why hybrid bearings are finding increased usage in a wide
variety of engineered applications toda
