Full full ceramic ball bearings

Full ceramic bearing magnetoelectricity insulation resistance, wear-resisting corrosion resistance, free of 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 silicon nitride (SI3N4) ceramic materials.Nanjing ABX Bearing Co.,Ltd.

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.

1, high temperature resistant: use the temperature in the "do not produce due to difference in temperature between 1000 degree expansion. Can be used in the furnaces, high temperature equipment such as plastic, steel;

2, 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.

3, 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.

4, electric insulation: high electric resistance, can avoid damage of bearing arc, available in various requirements of the insulation power equipment.

5, 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

1. A product profile of the zirconia (ZRO2) ceramic ball

Zirconia ceramic ball at room temperature with high strength and high toughness, good wear resistance, high temperature resistance, corrosion resistance, high stiffness, permeability, electrical insulation. Zirconia ceramics ball at 600 degree, strength and hardness is almost the same its density of 6.00 g/cm3, close to the metal thermal expansion rate if the inflation rate, can be used with metal joint.

2. The silicon nitride (SI3N4) ceramic ball product introductio

Silicon nitride ceramic balls are in the high temperature oxidation atmosphere sintering precision ceramics, high strength, high wear resistance, high temperature resistance, corrosion resistance, acid resistance, alkali, can be used in water medium, and has the good performance of insulation materials magnetic. At 800 degree, the strength and hardness is almost the same, its density is 3.20 g/cm3, is almost 1/3 of the bearing steel. Weight, rotating centrifugal force small. Can realize high-speed operation. Also have self lubrication, it can be used to no lubrication medium high pollution of environment. Become a ceramic bearing, hybrid ceramic ball bearing material of choice.

1: high grade: the hybrid ceramic ball bearing is the ball, is the use of ceramic ball (Si3N4), but theinner and outer rings are made of stainless steel, domestic and international brands 9Cr18,SUS440C grade. Advantages: high speed, flexible, durable; disadvantages: expensive.

2: the low-end: bearing steel bearing, material GCr15, 52100 international brands. Advantages: cheap; disadvantages: disposable.

3: by overloading is: full ball bearing, bearing no bearing retainer, are all steel ball. Advantages: can be overloaded; disadvantages: slow speed, can not withstand high speed.
