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.

Cold rolling mills are under pressure to produce more, higherquality steel. Equipment needs to cope with demands of greater dimensional accuracy, improved surface quality, higher steel grades and output speed. All this while overcoming the daily challenges of high precision, high loads, high speeds and aggressive coolants.
