Stainless steel guide rollers with xirodur® A500 ball bearings

For chemicals and heat

These stainless steel guide rollers can be used without any reservation in environments where temperatures are consistently as high as 302°F. The secret is the high-temperature ball bearings made of xirodur A500. This special material can be employed not only where temperatures are high, but wherever chemicals are used. Many of our customers in the food and chemicals industries are already using this technology. One example from the food industry is in artificial sausage skin manufacture, where drying areas experience high temperatures, and ball bearings made of other materials are not well-suited.

Self-lubricating endurance runner

Plastics are not necessarily incompatible with hot temperatures, as the Koppe example, below, shows. The pellet stove's operation is simple and ingenious. A mechanical drive unit moves the pellets without electrical energy through a cylinder resting on a roller into the combustion chamber for a burning time of around 24 hours. For the production process, Koppe was therefore looking for bearings for the drive mechanism that would work in adverse conditions without malfunctioning. The solution the company found was xiros polymer ball bearings made of temperature-resistant xirodur A500. This special material even allows brief high-temperature applications of up to 599°F, and because it needs no external lubrication, it runs smoothly over long periods. Metal ball bearings were out of the question. They seized immediately and generated an immense noise load.
