Tapered roller bearing
Abstract:
A tapered roller bearing includes an inner ring having an inner-ring raceway surface, an outer ring arranged radially outward of the inner ring so as to be concentric with the inner ring having an outer-ring raceway surface that faces the inner-ring raceway surface, a plurality of tapered rollers interposed between the inner-ring raceway surface and the outer-ring raceway surface; and a cage that holds the tapered rollers at predetermined intervals along a circumferential direction. A diameter of an inner peripheral surface of a small-diameter-side end of the cage is substantially the same as a diameter of a small-diameter-side pitch circle of the tapered rollers.
