high performance petroleum machinery ZrO2 full ceramic bearings 6202

high performance petroleum machinery ZrO2  full ceramic bearing 6202

Full ceramic bearing with diamagnetic electrically insulating, wear resistance and corrosion resistance, not self lubricating, high temperature resistance, cold and other characteristics, can be used in extremely harsh environment and special conditions.

The ferrule and the rolling body adopts zirconium oxide (ZrO2) ceramic materials, the retainer using Poly Tetra Fluoro Ethylene (PTFE) as standard equipment.

Rolling body and ferrule are made of Si3N4,the cage using polytetrafluoroethylene(PTFE) as the standard,at the same time,RPA66-25,PEEK,PI and phenolic fabric tube are available.Si3N4 full ceramic bearing compared to the ZrO2 material can be used in high speed and load capacity.and is suitable for high temperature environment.as well can provide for precision ceramic bearing spindle with high speed and high precision,high rigidity,high manufacturing precision up to P4 to UP.

professional show:

a) How to prolong service life of bearings?

     Accurate installation and using,alignment,timely monitor,re lubrication etc.

b) Reason for bearings failure?

    Usually is incorrect using method,pollution,improper use of lubricant,damage happened in installation and handing,also including installation error.according to the traces can know the reason why is failure.

c) How to choose bearings?

    Analyse mechanical device and use conditions.clear the requiremment of bearings.select type of bearings,select distribution way of bearings.selet dimensions of bearings,select installation method of bearings.

d)When select bearings specifications,what you need to consider?

    The precision of the bearings(rotating precision,dimensional tolerances)internal clearance and preload bearing material and heat treatment.structure of cage and material.
