Full ceramic bearing introduction:
Full ceramic bearings have the characteristics of anti-magnetic insulation, abrasion resistant,
oil-free self-lubricating and enduring extreme high or low temperature, so they can be used for
harsh environment and even under some special condition. The material of rings and rollers is
jar gonia (Si3N4) and the holder uses poly back fluoride(PTFE) as standard configuration.
Generally, we can use the reinforced nylon made of glass fiber 66(GRPA66-25), special
engineering plastics(PEEK, PI), nonrust steel(AISI SUS316 SUS304), brass(Cu) and so on.
Ceramic deep groove ball bearings are made entirely of ceramic material and are superior to
common Steel Angular Contact 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.
The advantages of ceramic deep groove ball bearing:
1) The ceramic bearing has the feature of corrosion resistance, the ceramic rolling
bearing suitable for operation under harsh conditions covered corrosion media.
2) Since the ceramic ball rolling has lower density than steel, so which is much lighter,
so when you rotate the outer ring centrifugal effect can be reduced by 40% ,
thus greatly extended service life.
3) The expansion and contraction of the ceramic affected smaller than steel, and
therefore the gap of the bearing is constant, the bearing allows the temperature
changes more severe environment.
4) As the ceramic has higher modulus of elasticity than steel, when the force is not
easy deformation, and therefore help to improve the operating speed and achieve
high accuracy.
