Pata mills for rolling of steel differ in many aspects with each other. The rolling mills are of different sizes and capacities and they roll steel materials of different cross-sections, sizes and qualities and in material conditions which are either hot or cold and they have different configurations and speeds of rolling.

These mills, with harsh operating conditions, need bearings that reduce friction and provide adequate support for effective rolling with minimum of energy loss. DYZV bearings are specifically designed to withstand high rolling loads, heavy shocks, varying speeds, and high temperatures. They also have enhanced contact surfaces and material strength properties that provide high performance so that the mill downtime can be reduced.
