Abstract: A dressing roll unit is supported on a nonrotating shaft clamped and maintained as a "fixed end" beam, thereby restrained against axial movement and deflection. The shaft is formed with spaced-apart bearing points, wherein wedge-shaped relief sectors are formed about the shaft at the bearing points, and a roll body is maintained about the bearing points with an annular clearance. Rotation of the dressing roll body and roll thereby forms high pressure hydrodynamic wedges of oil at the relief sectors and annular clearances, to create an extremely rigid roll mounting unit, without the need for pivoting bearing parts.
