ABSTRACT OF THE DISCLOSURE The present invention relates to a device for sealing shaft bearings or shaft-bearing housings as used, in particular, for self-aligning roller bearings used in rough-pressing rollers or the like, these incorporating a ring or sleeve-- advantageously of stainless steel--that encircles the shaft and having at least one annular projection on the outersurface, said projection extending into at least one annular groove at least one end of the bearing housing. According to the present invention, what is involved is a bearing housing, in particular a series or production bearing housing for operating conditions that make great demands on the bearing seal, that is economical to produce. According to the present invention, this has been achieved mainly in that the annular projection of the ring or sleeve that is installed in the housing and that surrounds the shaft with clearance that can be sealed off is fitted to the housing groove for the standard seal of series-produced bearing housings, and in that at least one, preferably two, annular recesses for shaft seal is/are provided on the inner surface, preferably on the face of the ring or sleeve.
