High Performance Full Ceramic Ball Bearing 6202 for Folding Bicycle

High Performance Full Ceramic Ball Bearing 6202 for Folding Bicycle

Ceramic bearings are compared with steel bearings:

1.Self-weight is 30% to 40% of steel bearings:It can reduce the centrifugal force of the operation, and the speed is 1.5 times of the steel bearing, the hardness is 1 times of steel, and the wear-resisting and anti-pressure is 5-7 times that of steel.The thermal expansion coefficient is less than 20% of the bearing steel.Friction coefficient is less than 30% of bearing steel, heat resistance, tensile and bending are equivalent to metal.

2.The maximum service life is five times longer than the steel bearing:Under the load, the centrifugal force decreases, the roller load decreases, the friction coefficient is small, reduces the operation temperature rise, reduces the friction, and extends the life of the raceway.

3.High speed ceramic bearing:It has the advantages of small force elasticity, light weight, small friction coefficient, high pressure resistance and cold tolerance.It can be used in the high-speed spindle and high precision equipment of 12000 RPM/min -75000 RPM.

4.High temperature ceramic bearing:Resistance to high temperature 1200 ºC, and good self-lubrication, temperature between 100 ºC to 800 ºC is not caused by temperature difference expansion.It can be used in high temperature equipment such as kiln, steel and smelting.

5.The magnetic:Ceramics are not magnetic, magnetic foreign objects and dust are not adsorbed, low noise and so on.Reduces wear and tear.Application in demagnetization, precision instrument and other equipment.

6.Corrosion resistance:Ceramics have the characteristics of corrosion resistance.Applied to chemical machinery, navigation ships, Marine operating machinery, electroplating equipment, electronic equipment and so on.

7.Electrical insulation:It can be used in insulation equipment.

8.Oil-free self-lubricity: The ceramic material has the characteristics of oil-free self-lubrication, which can prevent the lubrication of oil and grease and overcome the problem that the ordinary bearing cannot realize self-lubrication. Therefore, it can be used in high vacuum environment.
