The ”ideal Floating Bearing” for a highly loaded Calender Roll

The Finnish customer produces magazine papers, newsprint, fine and specialty


papers, as well as converted products and wood products. Challenge for Schaeffler
Shortly after the paper machine was first put into operation, several bearings in
the thermo rolls of the soft calender failed. Investigations showed that the main
cause of these failures was the axial load that acted on the bearings. Due to this
axial load, the two rows of rolling elements were loaded unevenly; as a result,
bearings were failing prematurely.
