Abstract

A bearing housing (3) encloses a bearing (2) for a shaft (1). The bearing is mounted on the shaft by a clamping sleeve (4) with a longitudinal slit and two flanges (5,6) one on each side of the bearing. The flanges, which are axially fixed on the sleeve, are parts of mounting and dismounting means for a bearing. The bearing space is sealed by sealing members which surround the flanges .[.and.]..Iadd., In a preferred embodiment, the sealing members .Iaddend.have lips (12,13) contacting the outer surfaces of said flanges. Resilient sealing rings (10,11) are arranged between the flanges and the inner ring of the bearing. The sealing arrangement allows the use of a slitted clamping sleeve and axial displacement of the bearing on the shaft (1) during mounting.
