• There is a bright and beautiful sightsee, no pollution, no harmful substance is released, and the surface is silver white gloss.
• Exquisite appearance, precision hydraulic, stable structure, polishing, no burr, round and beautiful
• Bearing steel has high and uniform hardness and wear resistance, and the elastic limit is high. The uniformity of the chemical components of the bearing steel, the content and distribution of non-metal inclusions, and the distribution of carbides are very strict.
• The hardness can reach HRC62-65 degrees, and the material is wear resistant. After cold processing into steel ball, the accuracy can reach 1/100,000 mm, and there is a mirror effect on the surface.
• 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.
