Ball 4.5mm

Model NO.: balls 1/2" Nominal Diameter: 6.35 Diameter: 4.763 HS Code: 8482910000 Application

The developing of chrome Steel ball (high carbon chrome alloy steel) is due to the poor performance of carbon steel ball used in the conditions of high loading and high rotation speed. Owing to its high hardness and wearresistant compared with carbon steel ball, it has longer lifetime. Therefore, it is usually used in the industrial products with high quality, high loading and high rotation speed.
