A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING MILL

Rolls are tools used in rolling mills to reduce the cross section of metal stock. The weight of rolls may vary from a few kilograms up to 250 tonnes. Under rolling conditions the contact area between roll and stock suffers wear, the other parts of a roll - body and necks - have to be considered as normal parts of designed components under high

The performance of a rolling element bearing is a function of the accuracy with which it is made; and the most accurate rolling element bearings are made on machines that use fluid films. In fact, the first machines used to grind rolling element b earing components used hydrodynamic bearings, where high speed relative motion between components caused a film of lubricant to build up between
