DSTR 1616, DSTR 4486, DSTR 4837 are just some of the codes of our customized back-up rolls for steel industry and back-up rolls for sheet metal flattening machines.
Back-up rolls and bearings: what are they?
The back-up roll is nothing more than a metal element that is used in the steel industry. In fact, these rollers operate in the production of sheet metal, in applications with heavy radial loads or even in those at high speeds.
Positioned above or below the leveling cylinder, in fact, the back-up roll carries out the task of retaining the bending of that element. Therefore, we can find the main utility of the composition precisely in its function as a bearing, which manages to contain the bending of the cylinder.
How to use the back-up rolls
There are many positions designed for back-up rolls, which are used in any steel or industrial sector. Most of the time, in fact, the back-up roll finds its place in tension flattening machines, for which it acts as a support and useful limit in moving the rollers and in good sheet metal processing.
The metal sheet, in fact, must be able to count on a well-done execution if it does not intend to run into a sudden slowdown in production (which costs time and economic resources).
Speaking of slowing production, it is necessary to know that behind a long and deleterious stop often hides the maintenance work of the machines, which are sometimes subject to downtime even for unscheduled interventions.
However, by purchasing quality back-up rolls, this obstacle can also be bypassed.
A quality back-up roll, for example, is able to distribute pressure better and therefore last longer over time, considerably reducing maintenance interventions.
Another solution to try are the back-up rollers with axial containment with cage, which also guarantee an excellent result in terms of duration and conservation.
Many others are, however, the things to check.
Let's find out how to enter the back-up rolls and bearings market.
Different types of back-up rolls
The materials which they are made with are of great importance (the most qualified Companies attest to their effectiveness through tests, which are carried out using reliable measuring equipment).
In addition to having to comply with the current safety regulations, the components can also change depending on the size or structure.
To really understand if a back-up roll fulfills the functions for which it was designed, also just pay attention to its thickness: a good back-up roll is generally made of thick steel, since it is on the structure that, most of the time, its capacity to handle loads and pressures depends.
