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 diameterxthe 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).
