<p>A tapered roller bearing (1) comprises an inner ring (2), an outer ring (3), a plurality of tapered rollers (4) rollably disposed between the inner and outer rings (2, 3) and a cage (5) for holding the tapered rollers (4) at predetermined circumferential intervals, wherein (the circumferential length on the PCD) - (roller diameter x the number of rollers) < roller diameter. Further, the tapered rollers (4) are uniformly disposed such that the distance between rollers on the PCD is less than (the roller diameter / the number of rollers).</p> |
