Material: GCR15

• Precision; advanced technology and sophisticated instruments ensure that the uniform error of each ball size is 0.001mm
• GCR15 authentic material; good performance after quenching and tempering, it has high and uniform hardness, good wear resistance, and high contact fatigue performance
• High adaptability, low noise, widely applicable to precision products
• High hardness; after quenching and tempering treatment, the uniform hardness of the surface can reach 62 degrees -65 degrees, with better compression and wear resistance.
• 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.
