Abstract
A tapered roller bearing () comprises an inner ring (), an outer ring (), a plurality of tapered rollers () rollably disposed between the inner and outer rings () and a cage () for holding the tapered rollers () at predetermined circumferential intervals, wherein (the circumferential length on the PCD)−(roller diameter×the number of rollers)<roller diameter. Further, the tapered rollers () are uniformly disposed such that the distance between rollers on the PCD is less than (the roller diameter/the number of rollers).
