Si3N4 ZrO2 Full Ceramic Ball Bearings , Ceramic Sealed Bearings 6020 2RS

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 roller 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.

What is the advantage of Ceramic ball bearings? 

Ceramic bearings have the normal steel balls replaced by white ceramic balls. The ceramic balls are made of solid silicon nitride. 

Ceramic silicon nitride balls are called ceramic but have nothing in common with household dish ceramics. They are called ceramic because it's easier calling them ceramic then silicon nitride. The ceramic silicon nitride ball is by far, smoother, harder, lighter and stronger than one made off steel.

Full Ceramic bearing Design Attributes :

• Design combines ceramic rolling elements with super finished steel rings to run faster, cooler and longer.
• Advanced design and materials help improve rigidity while reducing noise, vibration and operating temperature.
• Can be ordered with or without seals.
• Expanded options include custom preloads, 15° or 25° contact angles, and designs to ISO/ABMA 02, 10, 19 specifications.
