GCR15 Bearing Steel Beads 3.54mm 3.55/3.75/3.79 mm Steel Ball.-3.54mm300pcs(3.75mm)

Chromium bearing steel, main steel number GCR15; high carbon chromium bearing steel GCR15 is the largest bearing steel in the world, with carbon WC is about 1%, including Ming Ming's WCR is about 1.5%, accounting for the total number of world bearing steel production More than 80%.

• Hardness HRC63-HRC65 / has strong pressure resistance, wear resistant, cracks and carton do not appear in machine equipment
• GCR15 bearing steel ball / has high and uniform hardness and abrasion resistance, and high productive strength. The uniformity of chemical components is very strict
• Surface polishing process, the surface is like a mirror. The friction is reduced, the roundness is high, and the operation is smooth and reduced to damage to the machine.
• Tolerance is reduced by 0.002mm to meet high standard requirements for precision machinery.
• 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.
