The tensioning element type SE-W (marked with red dot) is equipped with heat-resistant elastomeric inserts. It is developed for applications in temperatures from +80° to +120°C (+180° to 250°F), such as belt tensioners for diesel engines, chain tensioners in driers, belt scrapers in hot surroundings, etc.

Due to the characteristics of the elastomeric compound, the resulting tension pressure of the type SE-W reduces by 40%, compared to the standard type SE and the type SE-G.
