Seal for rollers

摘要

A seal arrangement for rollers which permits axial displacement of a roller and its shaft with respect to their supporting bearing. A sealing ring which is generally L-shaped in cross-section has one radial arm of the L mounted on the shaft and against the roller, to provide a seal with respect to the roller. The other arm of the L extends axially away from the roller and has an outer circumferential surface which lies closely adjacent an inner surface of the bearing housing to provide a seal with respect to the housing. Lamellar rings may be provided between the bearing housing and the sealing ring.
