Bearing steel ball, size standard, high hardness, good roundness, wear resistance, smooth surface smooth can be used in high-speed bearing balls, hardware, electronics, toys, wrought iron, mechanical equipment, electricity, mines, metallurgy and other fields
Hardness can reach HRC60 or more
These bearing balls are installed between the inner ring and the outer ring to reduce friction when the bearing rotates. It can strength the protection to machine and extend the service life.[Applications]: It can be used in humid environments. Suitable for auto parts, bicycles, valves, refrigerators, air conditioners, bearings, photographic equipment, drawer slides and many other applications.
