Abstract
An assembly for journaling and sealing the shaft of a reciprocated roller in a printing press. Mounted on the shaft adjacent the roller is an anti-friction bearing which reciprocates with the shaft. A supporting sleeve is secured to the outer race of the bearing interposed between the bearing and the wall of the opening in the frame and telescoped over the projecting portion of the shaft, the sleeve being keyed to the frame to prevent relative rotation of the sleeve while permitting reciprocation of the sleeve with the shaft. A sealing ring has a collar which is recessed in the telescoping portion of the sleeve. The collar mounts on an annular lip of impervious resilient material extending therefrom cantilever-fashion and shaped to produce a narrow ring of contact with the projecting portion of the shaft, the lip being encircled by a garter spring so that sealing force is applied radially inwardly around the entire ring of contact. The collar of the sealing ring is fixed to the sleeve so that the ring of contact remains axially stationary with respect to the shaft as the shaft undergoes reciprocating movement.
