Engine ceramic bearing

Introduction
Ceramics axis as a kind of important bearing the mechanical foundation piece, since it has metal bearing the incomparable excellent properties which, high temperature resisting, extra strong in new materials such as outshine the rest of the world. During the past decade, and the people's livelihood in each domain got increasingly widely. Aviation, maritime, nuclear industry, petroleum, chemical industry, textile industry, machinery, metallurgy, electric power, food, locomotive, subway, high speed machine tool and scientific research defense military technology in fields such as high temperature, high speed, need cryogenic self-tightening, inflammable, explosive, corrosive, vacuum, electric insulation, no magnetic, and other special conditions dry friction work, ceramic bearing indispensable alternative role is being gradually understanding. As processing technology advances, craft level of increasing the cost of the ceramic bearing falling from the past, has only in some high-quality precisioninstrument, within the scope of application, small field gradually extended to all industries of national economy, product market prices also gradually is close to practical application, achieve the user an acceptable level of large ceramic bearing wave have flocked to application.

Advantages
1, as almost afraid of corrosion, so ceramic, ceramic roller bearing suitable for full of corrosive medium in the harsh conditions homework.

2, because the density of ceramic scroll balls than steel low, weight more much less, so rotates the centrifugal role of foreign circle, and then can reduce 40% service life greatly extended.

3, ceramic be heated bilges cold influence than steel small, so the bearing clearance must, allow bearing temperature changes in the more violent environment.

4, the elastic modulus because ceramic than steel high, while loading difficult deformation, thus to improve the speed of work, and achieve high precision.

Purposes
Ceramic bearing has high temperature resistance, cold resistance, abrasion resistance, corrosion resistance, resistance to magnetoelectricity insulation, no oil self-lubricating, high speed characteristics. Can be used for extremely difficult environment and special working conditions, can be widely used in aviation, spaceflight, navigation, petroleum, chemical industry, automobile, electronic equipment, metallurgy, electric power, textile, pumps, medical equipment, scientific research and defense military and other fields, and is the new materials application of high-tech products. Ceramic bearing rings and roller adopts full ceramic materials, zirconium oxide (ZrO2), Si3N4 (Si3N4), silicon carbide (Sic) 3 kinds. Keep device adopts teflon, nylon 66, polyether acyl and ammonia, zro2, si3n4, stainless steel or special aviation aluminum manufacturing, thus expanding the ceramic bearing applications.

Application

Medical devices, cryogenic engineering, optical instruments, high speed machine, high-speed motor, printing machinery and food processing machinery.

classification
(1) high-speed bearing: cold resistance, stress flexibility with small, resistance to pressure big, heat conduction performance is poor, light-weight, the advantages of small friction coefficient, which can be used in 12,000 R.P.M. - 75,000 R.P.M. high-speed spindle and other high-precision equipment; (2), high temperature resistant bearing: material itself has high temperature resistant 1200 °C, and self-lubrication good, using temperature at 100 °C - 800 °C caused by temperature difference between does not produce inflation. Can be used in the furnaces of plastic, steel, high temperature, such as equipment;

(3), corrosion resistant bearing: material itself with corrosion resistant properties, application in strong acid, strong alkali, organic and inorganic salt, water and other fields, such as: plating equipment, electronic equipment, chemical machinery, shipbuilding, medical equipment, etc.

(4), prevent magnetic bearings: because there was no magnetic not absorb dust, can reduce bearing early peel, large noise, etc. Available in demagnetization equipment. Precision instrument, etc.

(5), electric insulation bearing: for electric resistance is high, can avoid arc damage can be used in various requirements bearing the power equipment of insulation.

(6), vacuum bearing: for ceramic material alone without oil, since lubrication characteristics in ultra-high vacuum environment, can overcome the ordinary bearing cannot achieve lubrication problem. Note: the above five categories bearing, the same set of bearing can be applied to the high temperature, high speed, acid and alkali, magnetic field, the insulation, but due to material properties different (please refer to the rare earth ceramic material performance table) so please customers select products, applied occasion according to oneself, to select the most suitable ceramic bearing material.
