the description of FULL CERAMIC BEARINGS:
Full Ceramic Bearings are made entirely of ceramic material and are superior to common
steel bearings in many ways. Ceramic is the perfect material for any application seeking to
achieve higher RPM’s, reduce overall weight or for extremely harsh environments where high
temperatures and corrosive substances are present. Applications such as cryopumps,
medical devices, semiconductors, machine tools, turbine flow meters, food processing
equipment, robotics and optics. Ceramic materials commonly used for bearings are Silicon
Nitride (Si3N4), Zirconia Oxide (ZrO2), or Silicon Carbide (SiC.)
Because ceramic is a glass like surface it has an extremely low coefficient of friction and is
ideal for applications seeking to reduce friction. Ceramic balls require less lubricant and have
a greater hardness than steel balls which will contribute to increased bearing life. Thermal
properties are better than steel balls resulting in less heat generation at high speeds. Full
Ceramic bearings can have a retainer or full complement of balls, retainer materials used are
PEEk and PTFE.
Full ceramic bearings can continue to operate under extremely high temperatures and are
capable of operating up to 1800 Deg. F. Ceramic is much lighter than steel and many bearings
are 1/3 the weight of a comparable steel bearing. Full ceramic bearings are highly corrosion
resistant and will stand up to most common acids, they will not corrode in exposure to water
or salt water. And finally full ceramic bearings are non-conductive.
The purpose of a radial bearing is to reduce rotational friction and support loads. This is
achieved by using two races to hold the balls and to spread the load through the balls. As the
bearing race rotates it causes the balls to rotate. The ball provides for substantially less
rolling resistance and coefficient of friction than if two flat surfaces were rotating.
Single-row, Full ceramicl bearings are the most common bearing type, having a wide range of
applications. Radial bearings are made with very high levels of precision and used in
applications where rotational performance and low torque is necessary, but load is a
secondary issue. Full ceramic bearings however do have higher load ratings for their size than
shallow-groove ball bearings, but are also less tolerant of misalignment.
the characteristic of ceramic bearings:
(1).Low density
Due to the low density, ceramic bearings have low centrifugal load, and create little heat so
they can work in the conditions of higher speed.
(2).Suitable elastic ratio
The elastic ratio of ceramics is higher than that of steel, this can increase bearing’s dynamic
stiffness, however, the elastic ratio should not be too high, otherwise, excessive elastic ratio
will create stress concentration to decrease the bearing capacity.
(3)Low thermal expansion
This can make bearings insensitive to the changes of temperature, and is helpful to
preventing the bearings from being jammed. According to hybrid bearings, the applicable
rotation speed interval can be wider.
High strengthHigh compressing strength is the requirement of bearing high contact stress (for ceramics,
the compression strength are usually determined by the rupture modulus measured by
three-point or four-point bending strength )
(4)High hardness and high toughness
Ceramics have high hardness and high toughness can achieve good surface smoothness, and
can prevent the damage of impact and other outer particles.
(5)Good rolling fatigue performances
This performance is an absolutely necessary for bearings.
Flaking failure pattern
If the rolling element fails in the working, it should be fatigue flaking, this pattern has sign
before bearings being jammed, and is the least harmful failure pattern.
The ceramic bearings working in extreme conditions have some appended performances
Resistance to elevated temperatures and stability
Ceramic bearings can keep their mechanical stability up to 800°C.
(6)Corrosion resistance
In the conditions of oxidation and corrosion, especially the contact zone where the oil film
have been pushed off due to the repeat rotation, the material should have good oxidation and
corrosion resistance.
Application:
Full ceramic bearing could be used in following industries: chemical, semi-conductor, valve & pump, food, electronic, medical, vacuum, refining, insulation, etc
