摘要： A bearing unit having a sealed single-row deep-groove ball bearing. The sealed single-row deep-groove ball bearing includes an outer race ring with a sphered outer envelope surface, a housing with a sphered bore for accommodating the bearing, an inner race ring with a taper bore, and a correspondingly tapered clamping sleeve provided in the bore of the inner race ring and having a flange provided on at least one side of the bearing. The flange has at least one bore, and at least one tightening device for causing a force on the bearing inner race ring for displacing the inner race ring along the clamping sleeve thereby causing a clamping effect between the inner race ring and the sleeve and between the sleeve and a shaft on which the bearing unit is mounted. The bore of the flange includes a threaded through-bore extending at an acute angle with respect to an axial direction of an inner envelope surface of the sleeve. The tightening device includes a set screw arranged to contact a side face of the inner race ring.
