<P>PROBLEM TO BE SOLVED: To lower the maximum bearing pressure of a raceway surface by increasing load capacity without lowering the rigidity of a cage. <P>SOLUTION: This tapered roller bearing 1 is provided with an inner ring 2, an outer ring 3, a plurality of tapered rollers 4 arranged in a rollable manner between the inner ring 2 and outer ring 3, and the cage 5 for holding the tapered rollers 4 at predetermined spaces in a circumferential direction. In this case, a roller coefficient γ is made larger than 0.94, wherein γ: (number of rollers × roller average diameter)/(π×PCD). <P>COPYRIGHT: (C)2005,JPO&NCIPI |
