<p>A tapered roller bearing includes bearing rings including an inner ring (4) and an outer ring (3), a roller (1) rolling between the inner ring (4) and the outer ring (3), and a cage (2) having a pocket holding the roller (1) and located adjacent to the outer ring (3). A radial clearance ´ between the cage (2) and the outer ring (3) when the cage (2) is in a neutral position, a radial clearance ´ pr between the roller (1) held in the pocket and the cage (2), and a circumferential clearance ´ pc between the roller (1) held in the pocket and the cage (2) satisfy relations ´ pr >´ pc and -2‰ (´-´ pr )/(´ pr -´ pc )‰ 0.</p> |
