Description

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(ZrO2) 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.Related Models
