Rolling of hot strip and strip defectsIspatGuru

Jan 14 2017 · Mill spring is a defect in which the rolled strip is thicker than the required thickness since the rolls get deflected by high rolling forces. Elastic deformation of the mill takes place during rolling. Mill spring can be avoided if stiffer rolls are used which means that the roll material is having high stiffness or elastic constant.

Rolling-element bearingWikipedia

A rolling-element bearing also known as a rolling bearing is a bearing which carries a load by placing rolling elements (such as balls or rollers) between two bearing rings called races. The relative motion of the races causes the rolling elements to roll with very little rolling resistance and with little sliding.
