Tension rollers

Tension rollers are needed to achieve complex belt drive concepts and to set the pre-tension force with rotary drives.

Tension rollers are available as smooth and toothed tensioning rollers and idler pulleys, both with and without flanges. Tension rollers are also available with an eccentric cam or alternatively with a flange.

Please refer to the respective data sheet for more detailed properties of the individual tension rollers.

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.
