These roller guides are wider than standard guides and the roller bearing assemblies are fitted with SKF tapered roller bearings for heavy-duty applications. The two rollers next to the rolls, are extra low which admits the guide to be mounted as close as possible to the rolls. For 2-, 3-, 4- or 5-strand slitting, the width of the

In most rolling mill applications, four-row tapered roller bearings are mounted with a loose fit on the roll neck. This enables quick roll changes. However, loose fits have the disadvantage that the inner rings turn on their seats under load. To reduce the effects of a loose fit, SKF bearings have a helical groove in the bore and/or lubrication ...

Milling is the machining process in which the removal of metal takes place due to the cutting action of a rotating milling cutter.In a milling machine, the cutter is rotating due to workpiece is fed against it.This machine can hold more than one tool at a time. The cutter rotates at high speed, and because of the many cutting edges, it removes metal at a very fast rate.
