P5 High-Precision Bicycle Ceramic Ball Bearing 6000 6001 6900 6901 6902 6903 2RS

Hybrid ceramic bearings are mainly used in bicycle hub. In order to meet the needs of different users, we specially provide bearings with different precision levels. Mainly includes motor level (ABEC-3 P6);   。precision grade (ABEC-5 P5)

1.[Bearing steel mixed pottery] Motor grade: bearing steel material, national standard P6 Z2 or above. The dimensional accuracy is less than ± 0.01mm, the hand feels smooth, the rotating speed is 12000rpm, low noise and long service life. It is suitable for motors, toy models, automobiles, electric tools, pneumatic tools, telecommunications equipment, fitness equipment, sports equipment, etc.

2.. [Bearing steel mixed pottery] boutique grade: bearing steel material, national standard P5 or above. The dimensional accuracy is less than ± 0.005mm [can replace Import], feels smooth, rotating speed is more than 20000rpm, low noise, long service life. Applicable to high-speed motors, high-speed models, instruments, precision equipment, high-end toys and other fields with high requirements

bicycle bearing replacing metal materials such as steel with ceramic materials as rolling bodies aims to use Abrasion Resistant, corrosion resistance, high temperature resistance, electrical insulation (except SiC) that the former is better than the latter or that the latter does not have, non-magnetic conductivity, high strength, high rigidity, small specific gravity and other properties. The use of ceramic materials can make the bearing run normally in higher speed, more harsh environment and low lubrication occasions, reduce wear, reduce noise, reduce vibration, and make maintenance easier, so as to achieve a longer bearing service life and greatly improve its performance and reliability. Ceramic materials suitable for bearing

     1.bearing configuration :inner and outer ring bearing steel +SI3N4ceramic ball +PA66retainer +2RS

     2.shell grease

     3. advantages of Hybrid ceramic ball:

       1.oil-free self-lubricating, ceramic ball has oil-free self-lubricating performance, so ceramic ball bearings can be without grease

   2.insulation, the rolling body adopts ceramic balls, which can achieve insulation between the inner ring and the outer ring of the bearing.

   3.The rotating speed is high, and the rotating speed of ceramic ball is much higher than that of Pu bearing.

   4.Long service life, ordinary bearings are used in water and high temperature environment, and grease is easy to wash off or kill, so the bearings will soon break down. Using ceramic balls as rolling bodies, there is no need to worry about these problems.

   5.Waterproof: ordinary bearings are used in water, grease is washed off, and the bearings are broken quickly. Ceramic balls can be used in water normally.

4.Mainly used in: Bicycle skateboard pulley equipment, optical instruments, printing machinery, cryogenic engineering, food processing machinery and all kinds of rotating equipment. 。。
