contribute to many of the roll neck failures that occur in 2-HI mill work rolls or 4-HI mill back-up rolls. As a consequence, the market is demanding a rolling mills revamp to mitigate roll neck breakage in the fillet ring area under severe loading conditions. The choice of bearing selection can play an important and beneficial role in establishing a successful revamp solution. Technical ...

Roll bearings are to meet the basic need of the rolling mill which is the smooth rolling of the steel products. They are friction reducing devices which provide support to the rolls for effective rolling with minimum of energy loss. The bearings are designed to withstand high rolling loads, heavy shocks, varying speeds, and high temperatures.
