Ceramic Bearings of full Silicon nitride
Because of its high compressive strength, contact fatigue resistance that is superior to chrome steels, electrical resistivity and low coefficient of friction versus bearing steel, silicon nitride ceramic bearings can be widely used in lots of fields.
The rings are made by silicon nitride ceramics.The retainers are made by PTFE, GRPA66-25, PEEK, PI, Nylon66, Polyether acid sub-ammonia, stainless steel and phonemic textiles tube. Compared with ZrO2, full ceramic bearings made of Si3N4 are suitable to endure heavier load and higher temperature environment, which help to extend the application, such as high-speed bearings, high temperature bearings, corrosion-resistant bearings, shielded bearings, electrical insulation bearings and so on.
Ceramic bearing of full zirconia
Like silicon nitride, zirconia ceramic bearings are also anti-magnetic, insulating, oil-free self-lubricating, corrosion resisting and high speed. They work in terrible conditions while the ordinary bearings cannot be qualified, and much cheaper than silicon nitride. They are widely used in lots of fields too.
The rings are made by zirconia ceramic, zirconia balls are the main rolling material. The retainers are made by PTEF, nylon66, polyether acid sub-ammonia, stainless steel. They can be used as high-speed bearings, high temperature bearings, corrosion-resistant bearings,elec
Hybrid construction ceramic ball bearing
Ceramic ball especially Si3N4 have the following performance as low density, high strength, low friction coefficient, electrical and magnetism resistance, wear resistance, well rigidity, lubrication and maintenance free when working, it's the best choice for rollers(inner ring and outer ring are made by metal) of the hybrid construction ceramic ball bearing which are used in high-speed, high accuracy and long life environments. Normally, GCr15 or AlSl440C, 3163make inner ring and outer ring; The ceramic ball can adopt ZrO2, Si3N4.
