Abstract

To provide a pre-bending stress on a shaft (1) supporting a plurality of bearings (2, 3) which, in turn, support a roller sleeve (4), the shaft is fitted at the end portions thereof into a sleeve (5) formed with radial projections (6, 7). The sleeve is pivotably retained in a support holder (8, 9) having projecting jaws (8), fitting around the projections (6, 7) of the sleeve. Coupling pins or bolts (13) pivotably or tiltably interconnect the sleeve and the jaws. To provide a pre-stressing tilt against the ends of the shaft, engagement or adjustment screws (18, 19) can lock the projections (6, 7) extending from the coupling sleeve (5) in predetermined pivoted or tilted position with respect to the side walls (11) of the machine, to which the support holder (9) is secured. Preferably, a part-spherical interposed coupling is located between a head and counter nut of the adjustment bolts.
