product name
Full ceramic silicon nitride ball bearing
Product Description
Ceramic bearings are typically constructed with a ferrous inner and outer ring with
ceramic balls in stead of steel.They takes many advantages over steel bearings,
such as higher speed and acceleration capability, increased stiffness, lower friction
and more.Ceramic bearings are Ceramic bearing balls have smoother surface than
most steel bearings balls.They require less lubricant and exhibit lubrication
degradation, which results in increased bearing life.Ceramic bearings are applied
on high temperature, high speed, friction,semiconductor and food processing and
so on.
Advantages of Ceramic Bearings
(1)essentially increased life time
(2)high stiffness because of high Young’s modulus,lower vibration
(3)wear resistance and cost effective lubrication
(4)electrical insulation and non-magnetism
(5)high temperature resistance up to 1000oC
(6)high corrosion resistance to most acids and alkalies

Full ceramic bearing rings of silicon nitride and silicon nitride rolling elements (Si3N4) ceramic materials, maintaining PTFE, nylon 66, polyether imide, zirconia, silicon nitride, stainless steel or special aviation aluminum.
Silicon nitride ceramic bearings Features:
1, High speed: a cold, mechanical flexibility of small, anti-stress, poor thermal conductivity, light weight, low friction, etc., can be applied to 12,000 rev / min to 75,000 rev / min high-speed spindles and other precision equipment in;
2, temperature: material itself has a high temperature degrees 1200 ℃, and good self-lubrication, temperature at 100 ℃-800℃temperature difference between the result does not produce a result of inflation. Can be used in furnaces, manufacturing plastic, steel and other high temperature equipment;
3, anti-corrosion: corrosion-resistant material itself has the characteristics, can be applied to acids, alkalis, inorganic and organic salts, water and other fields, such as: plating equipment, electronic equipment, chemical machinery, shipbuilding, medical equipment and so on.
4, shielded: do not smoke because of non-magnetic dust, can reduce the bearing off in advance, and big noise. Available in the demagnetization device. Precision instruments and other fields.
5, the electrical insulation: resistance force high arc injury-free bearings, available in a variety of electrical equipment insulation requirements.
6, the vacuum: Because ceramic materials with unique self-lubricating properties of the oil, in an ultrahigh vacuum environment, silicon nitride ceramic bearings can not be achieved to overcome the plain bearing lubrication problems. -

FAQ
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.e) Payment method,packing way,transport method,time of delivery? T/T,PAYPAL,WESTERN UNION,L/C Tube,box,carton,pallet, By sea,by air 3-15days after receipt of payment.
