The ceramic bearing has anti-hig
htemperature, anti-coldness,
anti-corrosion,anti-magnetoelectricity and insulation,
non oil self-lubrication, high speed. It can be used in
awful environment and specially condition.It's commonly
used in aviation, spaceflight, navigation, petroleum,
chemical, auto-car,electronic apparatus,
metallury,electric-power, textile, pump,
medical-appliance, scientific research, national defence
these areas. It's a high-tech product using new
material.

The ceramic bearings, ring and roller
which produced by our plant are all taken full-ceramic
material. There are ZrO2,Si3N4 and Sic. The cage made by
telfon, nelon 66, polyimides, ZrO2, Si3N4, Stainless
Steel or special aviation aluminium, so it expands
ceramic bearing's apply area. Such as: high-speed
bearing, anti-high temperature bearing, anti-corrosion
bearing, anti-magnetic bearing and
anti-magnetoelectricity bearing. |
1.high-speed bearing: it has
anti-coldness, under-stress elastic small, anti press
big, bad heat conducation character, deadweight light,
friction factor small and other strong points. It can be
used in 12000RPM~~75000RPM high speed bearings and other
high precision equipements.
2.anti-high temperature bearing: the material itself
has the ablity of anti high temperature, can be up to
1200°C , and also has good self-lubrication character.
Use in the temperature of 100°C ~~800 °C it won't swell
because of the difference in temperature. It can be
widely used in
3.anti-corrosion bearing:the material itself has the
character of anti-corrosion. It can be used in strong
acid, strong alkali, inorganic salt and organic salt and
sea-water areas. Such as: plated equipment, electronic
apparatus, chemical industry, shipbuilding and medical
appliance.
4.anti-megnism: because non-magnism don't absorb in
dusty, it can be reduced bearings flake away in advance
or loud noisy and so on. It can be used in demagnetized
appliance, precise instrument and so on.
5.electric insulation bearing: because of its high
resistance, it can help electric arc don't demage the
bearing. It can be used in any kinds of electric
equipment which require insulation.
6.vacuum bearing: because ceramic has the non oil
self-lubrication, this unique character. In the super
vacuum space, it can get over the normal bearing can't
realize lubrication this difficult question.
Note: The
above bearings which we can supply, each bearing can be
uesd in high temperature, high speed, acid alkali,
magnism, non-insulation states, but cause different
meterial has different character(please check: The
performance sheet in thulium and ceramic material ).
So when you choose product please kindly let us know
your using place, we'll choose the best suitable ceramic
bearing. |

1.deep groove ball
bearing(technical class:P4,P5,P6,P0)
deep groove ball
bearing, the most reprensentative roller bearing, has
wide usage, can stand radial load and both way axial
load. It suits for high speed rotation and require low
noisy, low libration place or some areas which the
normal steel bearings can't stand, such as high
temperature, high coldness, corrosion, magnism and
non-insulation areas.
2.spherical bearing
spherical bearing's race of
the outring is spherical surface,auto regulation of
mental activities, it can add the non-coaxiality and
axial deflecion.It can be.
3.single row angular contact
ball bearing(technical class:P4,P5,P6,P0)
angular contact ball
bearing suits for high speed, high precise rotation. In
high temperature, magnism, and water don't affect its
precise,and can stands compound load.The standard
contact angular are 15°,30°,40°.The contact angular is
bigger,the axial load ablity is strongger.The contact
angular is smaller,bearing can stand radial load and
one-way axial load.Generally it takes gemination
install.Please take a note when you purchase.
4.one-way thrust
ball bearing
one-way
thrust ball bearing,it compounds of with ball roller
race's washer ring and cage with ball.It can stands
axial load,but can't stand radial load. |
The character of ceramic bearing material |
1.please check: Bearing material capacity
forum
2.compared with chrome
steel, its deadweight is chrome steel's 30%~~40%.It can
reduce dynamic load's increasing and sliding cause by
centrifugal force.Because its high anti-frication, speed
is chrome steel's 1.3~1.5 times,it can reduce the race
surface damage caused by high speed rotation. The
elastic measurement is chrome steel's 1.5times. Under
stress elastic is small, it can reduce the distortion
caused by high load.Its hardness is chrome steel's 1
time, can reduce the frication.And its anti-stress
character is chrome steel's 5~7times. Thermal expansion
coefficient is 20% less than chrome steel. The frication
coefficient is 30%less than chrome steel, it can reduce
the quantity of heat caused by frication and also can
reduce bearing flake away or useless in advance caused
by high temperature.Anti-pull,anti-bund,the same as
metal. |
Ceramic bearing's install |
Our company's ceramic bearing's inner race &
outer race and other dimensions are all the state steel
bearing P4,P5,P6's standards.Because ceramic meterial
thermal expansion modulus is low, character of transfer
heat is small and elastic measurement is small, please
pay a great attention on the installment.And welcom
consult us when you purchase, we'll choose the best
product to work in with tolerance. |
