Abstract

A sealed bearing arrangement for the ring rollers of a cold rolling mill is provided with a rolling bearing mounted on a journal of a rolling shaft and seated in the bore of a chock, and a pair of housing covers fastened to said chock on respective sides of said rolling bearing. Each of the housing covers has a bore in which a pair of sliding rings and a pair of O-ring seals are arranged. The sliding rings of each pair have mutually abutting end surfaces and respective outer conical circumferential surfaces which are resiliently supported by the respective separate O-ring seals. The O-ring seals in turn are supported by a conical bore surface formed on the corresponding housing cover and by a conical inner surface of a washer seated adjacent the inner ring of the bearing respectively. At least one shim ring is inserted between the side surface of a ring of the rolling bearing and a supporting shoulder surface of one of the housing covers or washers.
