Abstract: A bearing assembly for a shaft having a journal end portion (4) comprises a double-row taper roller bearing (B) with its inner races (36) engaged on the journal. An end cap (10) secured to the end of the journal holds a seal ring (22), the two inner races (36), a seal sleeve (24) and a backing ring (28) in abutment with each other and clamped against the shoulder. The seal sleeve (24) has an internal diameter greater than the diameter of the journal so as to leave an annular gap therebetween, and the seal sleeve is located radially by engagement of one of its ends in an interference fit in an annular rebate in the adjacent end of the backing ring. Seals are arranged between the end portions of the outer race and the seal ring (22) and the seal sleeve (24) respectively.
