Precision Steel Ball 4, 1/4, 2/4, 3/4, 4/4, 5/4, 6/4, 7/4, 8/4,763/4,9mm 1000PCS(4.9mm1000PCS)

Whether standard parts: standard parts

• Good product foundation is good steel, we use the highest-end steel to ensure the functional standards of steel balls, and use the total GR15 bearing steel to be machined.
• The appearance is precisely hydraulic, the structure is stable, and the polishing and polling is not lost.
• High hardness, wear resistance, steel density, uniform load capacity, increase life, reduce replacement and damage
• High precision rating, small friction coefficient, polished, smooth surface smooth, high brightness
• 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.
