Polyurethane timing belts have a high degree of resistance to lubricants, moisture and chemicals, and are particularly resistant to abrasion thanks to their special fabric sheathing. For this reason, the Walther Flender polyurethane timing belts conform to standards such as FDA and EU food approval.
The WF Flex polyurethane timing belts are designed as infinite extruded drive belts with a spiral-shaped rolled-up tension member in various sizes, versions and tooth shapes. The special manufacturing processes allows a high degree of flexibility in selecting the belt length, while still retaining full output and power transfer. The WF Flex drive belts also offer impressively synchronous running. Various coatings and possible special working make this drive belt the tailor-made drive element for your individual application.
The Walther Flender polyurethane timing belts are particularly suitable for use in the food industry, bottling and packing, nutrition and luxury foods, cleanroom technology and medical technology.


An optimum belt selection can never be made across the board; it must be based on the individual requirements of the application in question. If a specific drive belt that is adapted perfectly to the timing belt pulley is selected, the efficiency of both the timing belt drive and the entire drive train is improved.
