Abstract: A sealed bearing includes inner and outer race rings, roller members disposed therebetween, and built-in sealing members for sealing the space in which the roller members are situated. The outer race ring is equipped with a mounting groove 5 for each sealing member. The groove is situated axially inside of a side plane of the outer race ring and is inclined obliquely relative to that side plane. The mounting groove has an opening situated axially outside of the outer race track, whereas at least a part of the inner end of the groove is situated axially inside of the outer axial end of the outer race track.

Abstract: The invention related to a multiple-row roller bearing with a generally spherical outer ring raceway (2) and a guiding ring (5) between two rows of rollers, the guiding ring being centered in the bearing by contacting the outer ring raceway. In order to permit the part of the guiding ring which contact the rollers to be made of a material which is suitable from a wear and friction point of view, the guiding ring comprises an inner part (8) of such a suitable material. This part is closed and has a rotational symmetry, and its size allows it to be introduced into the outer ring of the bearing. An outer part (9) is arranged around the inner part and it can be mounted on the circumference of the inner part when the inner part is inserted in the outer ring of the bearing, whereby the outer ring fills up the space between the inner part and the raceway of the outer ring in at least some areas.
