New 1pc 6905 Full Ceramic Bearing ZrO2 Ball Bearing 25x42x9mm Zirconia Oxide

Full Ceramic Bearing ZrO2 Ball Bearing Zirconia Oxide 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 polytetrafluoroethylene ( PTFE ) as standard equipment 1. high speed : with cold resistance , stress resistance to pressure , small elastic , thermal conductivity , light weight , the advantages of small friction coefficient , can be applied to 12000 rpm to 75000 rpm for high speed spindle and other high precision equipment ; 2. high temperature resistant : use the temperature at 100 degrees to 600 degrees between the generated due to the range of temperature expansion . Can be used in furnaces , plastic, steel and other high temperature equipment ; 3. corrosion resistance : the material itself has corrosion resistance characteristics , can be used in strong acid , strong alkali , inorganic , organic salt , water and other fields, such as: plating equipment , electronic equipment , chemical machinery , shipbuilding , and other medical equipment . 4. because of no magnetic , magnetic dust absorption , can reduce premature bearing flaking , big noise . Available in the demagnetization device . Precision instruments and other fields . 5. due to electrical resistance , electrical insulation , can avoid arc damage bearings , can be used in a variety of insulation of power equipment . 6. because of the unique ceramic materials , vacuum oil-free self-lubricating property , in ultra-high vacuum environment , zirconia ceramic bearings can overcome the plain bearing can not realize the problems of lubrication . Main uses : Medical equipment , optical instruments , printing machinery , machine tools, high-speed motor , low temperature engineering , food processing machinery Item Description: Item: 6905 Full Ceramic Ball Bearing Type: Full Ceramic Ball Bearing Cage: PTFE Balls: ZrO2 Ceramic Inner/outer races: ZrO2 Ceramic Dimensions: 25mm x 42mm x 9mm/Metric ID (inner diameter)/Bore: 25mm OD (outer diameter): 42mm Width/Height/thickness: 9mm Package: 1pcs Full Ceramic Bearing ZrO2 Ball Bearing Shipping Description： Item will be shipped by airmail with tracking number (ship to USA by USPS epacket delivery ) within 24 hours(1 working day) after full payment is received.
