Abstract
Sealed bearing incorporating an inner race (13) an outer race ring (14) and a row of elongated rollers (15) disposed between, whereby races (11, 12) and rollers (15) have curved longitudinal section profiles and which rollers (15) are axially moveable between the races relative thereto for allowing mutual misalignment of the races, and whereby at least one sealing member (18) is formed separately, positioned axially outside the rollers (15) but adapted to follow the rollers (15) in a free-floating manner and arranged to provide its sealing effect by frictional engagement, wherein at least one of the inner and outer race rings (13, 14) at the axial outer ends of its race (11, 12) is each provided with a radially projecting motion preventing means (20) of short axial width, arranged to prevent the sealing member (18) from being pressed out from the space between the bearing race rings even at misalignments of the race rings (13, 14) relative to each other.
