Technical Information for toothed belts 22052, 22054, 22057 and 22059 General Our toothed belts are made of abrasion-resistant polyurethane and reinforced with hightensile steel cording. They allow for a smooth and synchronous transmission of power. They are maintenance-free and extremely cost-efficient. Drive installation Diagrams and performance tables are available on these pages for selecting the size. The axles must be parallel to one another. It is possible to align the toothed pulleys very precisely using a straight edge or laser. Use the largest possible toothed pulleys. Make sure...
