A roll having a curved stationary axle carries a series of bearings which rotatably mount a roller sleeve. The bearings, which have to fit the axle loosely, are held firmly in place by an axial stack of annular spacer collars and axially-compressible spring spacers, which apply a controlled compression. Optionally, deformable cushioning rings are compressed against the bearings by the collars. The cushioning rings may be made of a material which is either compressible or incompressible; the spacers have expansion chambers at their ends to accommodate deformation of the rings if these are incompressible.
