This kind of 6.5mm Bearing Steel Ball uses the world's leading anhydrous production process, that is, completely dry resin sand is applied on the metal film, completely avoiding forging problems such as porosity or slag inclusion caused by water glass moisture, which greatly improves the product quality and Iron-carbon ratio, as far as possible to meet the quenching needs. In addition, the surface of the 6.5mm Bearing Steel Ball is smooth, and the area of the riser occupies a small total surface area of the steel ball, which effectively reduces its inefficient abrasion at the riser, which also helps reduce energy consumption and enhance production output. Besides, it has the advantages of high precision, small size, smooth surface, delicate design, low costs, high cost effective, wear resistance and durability. The 6.5mm Bearing Steel Ball is very popular with our customers worldwide.
