Abstract

PURPOSE: To block the intrusion of foreign materials transmitted along engagement surfaces between inner rings of the bearing and the shaft, by closely sealing the place at face-to-face ends position between axially arranged inner rings through the seal unit installed over each circumferential groove formed on the inner circumferential face at an end part of the inner ring.
CONSTITUTION: The multi-row roller bearing comprises a plurality of inner rings 1 having outer trancks 11 and a plurality of outer rings 2 having inner tracks 21 in a face-to-face relation with the outer track 11 of the inner ring 1. Here in the inner ring 1, a cylindrical part 13 axially extended following a small flange 12 respectively at one end side as a use for the seal unit is constructed to form a small flange 14 at the other end side. And on the inner circumferential face at an end part of the small flange 14, is constructed a circumferentially stepped part 141. To said circumferentially stepped part 141 is installed a seal unit 6 having circumferential grooves 611 respectively on the peripheral faces at the end parts of a seal holding member 61 and consisting of elastic seal rings 62 placed in the circumferential grooves 611. In this way, the elastic seal ring 62 is closely contacted to the inner circumferential face, that is, one of the surfaces of the circumferentially stepped part 141 to closely seal the place interfaced with the inner ring 1.
