Rubber, PU or steel rollers

How to choose the right roller material for your welding rotator?

In our product range you will find six different models of welding rotators. These are suitable for different workpieces and applications. For example, the D-TLRS and the D-HGZ are better suited for thin-walled workpieces due to the double amount of self-adjusting rollers, as the pressure can be better distributed. Thus, each model has its suitable areas of application. But how do you choose the right roller material? 

We supply our standard machines with polyurethane (PU), rubber (in steel frame) or steel rollers. The material of the workpiece is decisive for the choice. We recommend PU for workpieces made of stainless steel and rubber or steel for workpieces made of steel.

Another important factor is the temperature of the workpiece. Rubber rollers can withstand temperatures of up to 150 °C, while PU rollers can only be used up to a temperature of 80-90 °C. 

At very high tonnages, PU or rubber can no longer withstand. In this case, there is also the option of choosing all-steel or wider roller. As mentioned above, our rubber rollers come standard with a steel frame for reinforcement, but we can also supply solid rubber on request. These are not standard solutions. Optionally, a lot is technically possible.

The right choice always depends on the application. If you need advice, we are happy to help. Call +31 541 533 369 or send an e-mail to info@dumeta.nl.
