<P>PROBLEM TO BE SOLVED: To provide a tapered roller bearing for a roll neck that has an elongated service life even if used under an environment where the possibility of water intrusion into the interior thereof is high. <P>SOLUTION: The tapered roller bearing 10 for a roll neck includes: a plurality of outer rings 11, 12 on the inner peripheral surface of which track surfaces 11a, 12a are provided; a plurality of inner rings 13, 14 on the outer peripheral surface of which track surfaces 13a, 14a are provided; and a plurality of tapered rollers 15 disposed between the track surfaces 11a, 12a and the track surfaces 13a, 14a. The relation between the length L of the tapered rollers 15 in the axial direction and the diameter D of the large diameter end 15a of the tapered rollers 15 is set at L<D. <P>COPYRIGHT: (C)2012,JPO&INPIT |
