The rolling elements, shaped as balls or rollers, provide the cushion that eases the moving friction of the shaft within its housing. These elements keep the outer and inner races separated and enable them to move smoothly and freely. The shape of the rolling elements depends on the type of load, operating conditions and particular applications. It is the rolling elements that distinguish the ...

even less rolling stages, e.g. when producing thin foil or beverage canstock. When continuous casting was first introduced it appeared to have many advantages which result to production economies.

The Complete Technology Book on Hot Rolling of Steel

The hot rolling technology is the most widely used method of shaping metals and is particularly important in the manufacture of steel for use in construction and other industries. In metalworking, rolling is a metal forming process in which metal stock is passed through a pair of rolls. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is ...
