Spreader rolls

Spreader rolls are used in the wet and dryer sections as well as in the finishing/converting processes. They consist of up to 25 sections which are arranged on a bent axle. The loads acting on the rotating outer rings of the deep groove ball bearings are low.

The bearings are lubricated for life. Depending on the position, ambient temperatures vary between 40 and 150 °C. Today hybrid deep groove ball bearings with a reduced number of balls are used in modern big machines in order to reach longer running times.

  • Speed ~1300 1/min
