ABSTRACT:
In a roll having a hollow roll through which a stationary cross piece extends, a bearing housing is provided for a bearing which engages an axial extension of the hollow roll. The extension has a smaller outer diameter than the outer diameter of the hollow roll. The bearing is located in the bearing housing between the outside circumference of the extension and the inside circumference of the bearing housing. The bearing housing has lubricant feed and discharge passages separate from means for hydraulically supporting the hollow roll. The bearing housing has a bore which fits over the end of the cross piece without play thereby forming a support distance.
