Abstract
Self-aligning roller bearing (1) which features, an inner bearing ring element (2), an outer bearing ring element (3), at least a series of roller elements (4) arranged between the inner and outer bearing ring element (2, 3), wherein the inner bearing ring element (2) has a retaining flange (21) provided on a first axial side of the roller bearing (1), wherein the retaining flange (21) is designed to prevent the roller elements (4) from falling out of the roller bearing (1) through a first axial opening (Ax) between the inner and outer bearing ring elements (2, 3) on the first axial side, wherein the roller bearing (1) further comprises a first sealing ring element (5) which is arranged on the first axial side for sealing the first axial opening (Ax), wherein the first sealing ring element (5) is rotatable with respect to the inner bearing ring element (2) and seals against a sealing mating surface (23) of the inner bearing ring element (2), wherein the retaining flange (21) provides at least one filling recess (22) designed to allow the roller elements (4) to be inserted between the inner and outer bearing ring elements (2, 3) during the assembly of the roller bearing (1), and the sealing surface (23) is arranged axially outside the at least one filling recess (22).
