This Hardened Steel Ball Bearings with High Precision is made from bearing steel. Bearing steels have high and uniform hardness and wear resistance, as well as high elastic limits. All balls must be passed the procedure of passivation. Each procedure have professional inspector. They will check steel balls each two hours to be sure correct diameter and good surface. So the surface of the Hardened Steel Ball Bearings with High Precision is smooth and shiny. What's more, this product has good resistance to wear, corrosion and rust. So the steel balls can give a long service life without anty maintenance cost.
