ABSTRACT:
To provide a snug-fitting bearing for journalling the spindle end of a printing press cylinder, a flanged bearing sleeve is disposed in a bore in the press frame and an anti-friction plastic material which compensates for the bearing play is injected into an external annular groove in the bearing sleeve of considerably less width than the depth of the bore in the press frame. Preferably, the bore is pretreated with a volatile release agent and the plastic material cures in situ to become a narrow bearing ring in the groove. The bearing sleeve may have eccentric annular shoulders on either side of the groove and a thin annular metal bushing may be interposed between the cylinder spindle and the interior of the sleeve bearing.
