R144 Dental Handpiece Stepped Ceramic High Speed Ball Bearing 50000 rpm

Zirconia(ZrO2) all-ceramic bearing:

Zirconia(ZrO2) all-ceramic bearing has the characteristics of anti-magnetic insulation,wear-resisting and corrosion-resistant,oil-free self-lubrication,high temperature and cold resistance,etc.The expansion caused by temperature difference does not occur in the temperature range of 100℃to 600℃for a long period of time.Can be used in strong acid,strong alkali,inorganic,organic salt,seawater and other extremely harsh environment and special conditions,rings and rolling element using zironia (ZrO2) ceramic materials.The protector uses(PTFE) as the standard configuration,and can also use fiberglass strong nylon 66(GRPA66-25),special engineering plastics(PEEK,PI),stainless steel(AISI SUS316,SUS304),brass(Cu),etc.

Silicon nitride(Si3N4) ceramic bearing:

Silicon nitride(Si3N4) ceramic bearing with diamagnetic electrically insulating,wear resistance and corrosion resistance,self-lubricating oil free,high temperature resistance,alpine characteristics.Comparision of zirconia (ZrO2) material can be applied to high speed and capacity,applicable to the more servere working conditions and higher ambient temperature,long-term use of temperature at 100 degrees to 800 degrees between the generated due to the range of temperature expansion.at the same time can provide for high speed and high accurancy and high rigidity of spindle of precision ceramic bearing,high manufacturing accurancy of P4 to up grade. Silicon nitride ceramic bearing rings and rolling body adopts the silicon nitride (Si3N4) ceramic materials,the retainer using polytetrafluoroethylene(PTFE) as standard  equipment in general can also use GRPA66-25,PEEK,PI,and phenolic cloth Bakelite Tube etc.

Hybrid Ceramic Ball Bearing:

Ceramic ball has the characteristics of low density,high hardness ,low coefficient of friction,anti-magnetic insulation,wear-resisting, self-lubrication and good rigidity. General speaking,Hybrid ceramic ball bearings  use chrome steel rings or stainless steel rings, balls can be in ceramic ZrO2,Si3N4,or SIc. Compare to ordinary stainless steel or chrome steel bearings ,hybrid ceramic bearing’s speed  can be increased to 1.5 times,service life increased to 2 to 3 times,can adapt to higher service temperature.
