Product Description
Ceramic bearing as an important basis of mechanical parts, since it has the excellent properties of metal bearing can not reach, resistance to high temperature, such as extra strong in the material world. For nearly 10 years, in the various fields of national economy and people's livelihood is becoming more and more widely used. Aerospace, Marine, nuclear industry, petroleum, chemical industry, textile industry, machinery, metallurgy, electric power, food, locomotive, subway, high speed machine tools and scientific research and national defense military technology need to be in high temperature, high speed, cryogenic, inflammable, explosive, corrosive, vacuum, electrical insulation, non-magnetic, and other special work under the conditions of dry friction, the ceramic bearing indispensable alternative role is gradually known by people. Along with the advance of processing technology, craft level is increasing day by day, declining the cost of the ceramic bearing, has been from the past only in some small high, refined, pointed areas within the scope of application, gradually extended to the national economy each industry, product market prices are also gradually close to the practical application, reach the level of user acceptance, the application of ceramic bearing large wave is coming!
My company's ceramic bearing are: zirconia (ZRO2) ceramic bearing, the highest temperature can reach 500 degrees;
Silicon nitride (SI3N4) ceramic bearing, the highest temperature can reach 1200 degrees.Ceramic bearing mainly: (1) the corrosion resistance performance. Resistant to acid and alkali, under the environment of acid alkali is used as usual;
(2) high temperature resistant. Low resistance to cold
(3) the oilless self-lubrication, do not need to add any grease
(4) wear-resisting, ceramic materials, low friction coefficient, especially in the silicon nitride
(5) high speed
1. The zirconia ceramic bearing
Full ceramic bearing magnetoelectricity insulation resistance, wear-resisting corrosion resistance, oilless self-lubrication, characteristics such as high temperature resistance, cold resistance, can be used in extremely harsh environment and the special operating mode. Ring and roller adopts zirconia (ZrO2) ceramic materials, retainer use teflon (PTFE) as standard, generally can also use glass fiber reinforced nylon 66 (GRPA66-25), special engineering plastics (PEEK, PI), stainless steel (AISI SUS316, SUS304), brass (Cu), etc.
2. The silicon nitride ceramic bearings
Silicon nitride ceramic bearings with zirconia ceramic bearings with all performance. Ring and roller adopts silicon nitride ceramic materials retainer using poly (ethylene (PTFE) as standard, four Buddha generally can also use glass fiber reinforced nylon, special engineering plastics, stainless steel, brass, silicon nitride materials than zirconia materials is more suitable for high speed rotation and large load, and the higher ambient temperature.
3. The full full ceramic ball bearings
Full ball full ceramic bearing side with ball gap, with no cage structure design, can be more than standard bearing load of the structure of ceramic ball, thus improve the radial load capacity, also can avoid the cage material limit, can achieve the ceramic type cage full ceramic bearing corrosion resistant and temperature resistant effect. This series of bearing is not suitable for high speed, when installation should pay attention to the gap surface mounted on one end of the don't carry axial load. Because of the bearing inner and outer ring gap filling ball, it was not suitable for large axial load application occasions.
Full ceramic bearing magnetoelectricity insulation resistance, wear-resisting corrosion resistance, free of self-lubrication, resistance to high temperature, cold and other characteristics, can be used in extremely harsh environment and the special operating mode. Ring and roller adopts zirconia (ZrO2) ceramic materials, retainer use teflon (PTFE) as standard, generally can also use glass fiber reinforced nylon 66 (GRPA66-25), special engineering plastics (PEEK, PI), stainless steel (AISI SUS316, SUS304), copper (Cu), etc.
Features:
1, high-speed: with cold resistance, small mechanical elasticity, resistance to high pressure, poor thermal performance, light weight, the advantages of small friction coefficient, can be used in the 12000 RPM to 75000 RPM of the high-speed spindle and other high precision equipment;
2, high temperature resistant, use temperature between 100 ºC to 600 ºC is not caused by temperature difference expansion. Can be used in the furnaces, high temperature equipment such as plastic, steel;
3, corrosion resistance, material itself has the property of corrosion resistance, can be used in strong acid, strong alkali, inorganic, organic salt, water, and other fields, such as electroplating equipment, electronic equipment, chemical machinery, shipbuilding, medical equipment, etc.
4, antimagnetic, because there was no magnetic dust absorption, can reduce the bearing early spalling, large noise, etc. Available in the demagnetization device. Precision instruments and other fields.
5, electric insulation: high electric resistance, can avoid damage of bearing arc, available in various requirements of the insulation power equipment.
6, vacuum: ceramic material unique oilless self-lubrication properties, in the ultra high vacuum environment, zirconia ceramic bearings can not overcome the ordinary bearing lubrication problem.
Main application:
Medical apparatus and instruments, optical instruments, printing machines, high-speed machine, high-speed motor, cryogenic engineering, food processing machinery
All silicon nitride ceramic bearing ring and roller adopts silicon nitride (Si3N4) ceramic materials, retainer use teflon (PTFE) as standard, also can be used commonly GRPA66-25, PEEK, PI, and phenolic fabric bakelite tube, etc. Compared SiN4 system full ceramic bearing ZrO2 materials can be applied to a higher speed and load capacity, and is suitable for the higher ambient temperature.
