Abstract
A rotatable roller arrangement is described, especially for rapidly-rotating rollers intended for abutment pressure such as roller guide rollers in rolling mills, which is rotatably journalled on a stationary shaft by means of at least two ball bearings situated symmetrically inside the roller on both sides of a shoulder arranged inside said roller. The shoulder, defining the axial positions of the bearings in the roller, has the shape of a ring which is held in a cylindrical bore for the same and the bearings pass through the roller, said bore surrounding the shaft. The outer and inner rings of the bearings are movable in the cylindrical bore of the roller and on the shaft, respectively, and are axially urged away from the shoulder-forming ring inside the roller.
