Main applications:

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

Application areas:

Medical instruments, 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, light textile industry, machinery, metallurgy, electric power, food, locomotives, subways, high-speed machine tools and scientific research and defence and military technology and other fields need to work in high temperature, high speed, deep cold, flammable, explosive, strong corrosion, vacuum, electrical 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, technology level is increasingly improved, the cost of ceramic bearings continue to decline, has been from the past only in some high, fine, sharp areas of small-scale applications, and gradually spread to various industrial areas of the national economy, the product market price is also gradually approaching practical, to the extent that the user can accept, ceramic bearings have been applied to a large area of the tide has come!

 

 

The Si3N4 ceramic bearing rings and rolling elements are made of silicon nitride (Si3N4) ceramic material and the cage is made of polytetrafluoroethylene (PTFE) as standard, but GRPA66-25, PEEK, PI and phenolic clad wooden tubes can also be used. 

 

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

 2, high temperature resistance: ceramic bearings with retainer use temperature between 180℃~260℃ does not produce expansion caused by temperature differences. Full ball silicon nitride ceramic bearing temperature in 800℃~1000℃, can be used in the furnace, plastic, steel and other high-temperature equipment.

 3, self-lubrication: ceramic bearings due to the friction coefficient is small, the surface smoothness is good, so has a good self-lubricating properties, especially 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 problem of ordinary bearings can not achieve lubrication. 
 
   4, anti-magnetic: because of the non-magnetic does not absorb dust, can reduce the bearing early flaking, noise, etc.. Available in demagnetization equipment. Precision instruments and other fields.

   5、Electrical insulation: Because of the high electrical resistance, it can avoid arc damage to the bearing, and can be used in various electric equipment requiring insulation.
