Toothed
The necessary pre-tension force can be simply and quickly set with tension rollers equipped with an eccentric cam.
Type B tension rollers have a toothed surface and are seated twice on grooved roller bearings. Thanks to the use of high-performance saponified grease, the bearings are greased for life and can be used up to a permanent temperature of 70°C without this reducing the useful life of the grease. These tension rollers are also short-term temperature resistant up to 120°C.
Please refer to the respective data sheet for more detailed properties of the individual tension rollers.
