Ceramic bearings have the characteristics of high temperature resistance, cold resistance, abrasion resistance, corrosion resistance, anti-magnetic electric insulation, oil-free self-lubrication, high speed and so on. Can be used in extremely harsh environments and special working conditions, can be widely used in aviation, aerospace, navigation, petroleum, chemical industry, automotive, electronic equipment, metallurgy, electric power, textile, pumps, medical equipment, scientific research and national defense and other fields, is a new material application of high-tech products.

Application fields:
Medical devices, cryogenic engineering, optical instruments, high-speed machine tools, high-speed motors, printing machinery, food processing machinery.

In the aerospace, navigation, nuclear industry, petroleum, chemical industry, textile industry, machinery, metallurgy, electric power, food, locomotives, subway, high-speed machine tools and scientific research and national defense and military technology and other fields need to be in high temperature, high speed, deep cold, flammable, explosive, strong corrosion, vacuum, electric insulation, non-magnetic, dry friction and other special working conditions, ceramic bearings indispensable alternative role is being gradually recognized.
With the continuous progress of processing technology, the increasing level of technology, ceramic bearing costs continue to decline, has been from the past only in some high-precision, pointed field of small-scale application, and gradually extended to the national economy in various industrial areas, the product market price is gradually approaching the practical, to the extent that the user can be accepted, ceramic bearings, large-scale application of the wave has been coming!

Silicon nitride ceramic bearings in detail:
Silicon nitride full ceramic bearing rings and rolling body with silicon nitride (Si3N4) ceramic material, keeper use polytetrafluoroethylene (PTFE) as standard configuration, generally can also use GRPA66-25, PEEK, PI, and phenolic cloth gum wood tube, etc. SiN4 full ceramic bearings compared to the ZrO2 material can be applied to higher speed and load capacity, as well as applicable to higher ambient temperatures. ambient temperatures. 

Characteristics:                                                                                                                                                         
  1, corrosion resistance: the material itself has the characteristics of corrosion resistance, can be used in strong acids other than hydrofluoric acid, strong alkali, inorganic, organic salts, seawater and other fields, such as: electroplating equipment, electronic equipment, chemical machinery, shipbuilding, medical equipment and so on.

 2, high temperature resistance: ceramic bearings with keepers are used at a temperature of 180 ℃ -260 ℃ without the expansion caused by temperature differences. Full ball of silicon nitride ceramic bearings using temperature of 800-1000 ℃, can be used in furnaces, plastic, steel and other high-temperature equipment;

 3, self-lubricating: ceramic bearings have good self-lubricating performance due to small friction coefficient and good surface smoothness, especially the silicon nitride material lubrication performance is better! So ceramic bearings do not need to add any grease. In the ultra-high vacuum environment, ceramic bearings can overcome the ordinary bearings can not realize the problem of lubrication. 
 
   4, anti-magnetic: because non-magnetic does not absorb dust, can reduce the bearing early spalling, noise and so on. Available in demagnetization equipment. Precision instruments and other fields.

   5、Electrical insulation: Because of high electric resistance, it can avoid arc damage to bearings, and can be used in all kinds of electric equipment requiring insulation.
