Abstract: A roll-journal bearing mounting is provided by a movable bearing housing from which pistons rigidly extend in opposite directions into cylinders rigidly fixed against displacement. Introduction of pressurized fluid to the cylinders moves the bearing housing either way in the direction of the pistons and cylinders. Consequently, a roll journaled by bearings in the bearing housings of two of the mountings can be moved towards and from a counter roll to apply roll nip pressure. At the same time the rigidly extending pistons in their rigidly fixed cylinders also function to hold the journal loading in a right angular direction, eliminating the need for the use of separate devices for that purpose.
