Good Price China Flange Bearing F687 7*14*5 mm

Material of ball bearing

1) Carbon steel   It is characterized by its low price and not asking too much for applications, so it is highly appreciated by the vast number of merchants. It is widely used in household appliances, electrical tools, pneumatic tool, textile machines, medical instruments, sport equipment, office furniture, packing machine, fishing gear, toys, sliding doors and windows, etc.

 High - carbon steels are being called the " hard ",which possess excellent wear resistance ,strength ,rigidity, good elastic and fatigue limit(especially the notch fatigue limit).

Medium- carbon steel has higher rigidity but lower deformation and toughness compare with low- carbon steel.

Low- carbon steel It is characteristic of low strength and rigidity, good deformation and toughness.

2) Chrome steel Chrome steel has feature of tensile. fatigue, wear resistance , high rigidity and great toughness. It can meet the requirements of corrosion and high - temperature resistance under certain conditions. Vacuum degassed Chrome steel GCR15 is a type of standard material for producing accurate inner ring, outer ring and ball. This material is in conformity with the specifications of AISL 52100(America),DIN100Cr6(German) and JISSUJ2(Japan).As there are less interferences from impurities, significantly extending the life span and   effectively improving the bearing’s torque and noise reduction property.

4) Ceramics Heat ,wear, corrosion resistant, insulated, anti – electromagnetic, anti - moisture , high rotation speed, etc. Especially it is to the atrocious conditions. The contexts of usage is cover various fields, aviation, voyage, oil, chemical, car, electronic equipment, textile, medical equipment instruments, toys, etc.
