Chrome Steel Bearing Balls in All Sizes
Metal balls are rolling, spherical elements that are used in check and ball valves, bearings, and other mechanical devices that provide rotary or linear motion. They are usually made from alloy steel, carbon steel or stainless steel. Metal balls are characterized by the Outer Diameter, Permissible Deviation, Surface Roughness and Tolerance. The Outer Diameter (OD) is the overall width or average diameter of the ball.
