The minimum bend radius is the radius below which an object such as a cable should not be bent. The diagram to the right illustrates a cable with a seven-centimeter bend radius.Ĭable with a seven-centimeter bend radius The smaller the bend radius, the greater the material flexibility (as the radius of curvature decreases, the curvature increases). Bend radius, which is measured to the inside curvature, is the minimum radius one can bend a pipe, tube, sheet, cable or hose without kinking it, damaging it, or shortening its life.
