Ceramic ball bearing NN3008K introduction :

     Full ceramic ball 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 roller is jargonia(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.

Ceramic ball Bearing Benefits :

• Will not corrode or rust
• 2/3 the weight of steel
• Resistant to resist acids, alkali, blood, salt and water
• Extremely low coefficient of friction and thermal expansion
• Lower friction results in less energy consumed
• Operating Temperature from as low as (-85°C) up to (+ 900°C)
