PROBLEM TO BE SOLVED: To lower a maximum bearing pressure on a raceway surface by increasing a load capacity without lowering the rigidity of a cage. SOLUTION: This tapered roller bearing 1 comprises an inner ring 2, an outer ring 3, a plurality of tapered rollers 4 rollingly disposed between the inner ring 2 and the outer ring 3, and the cage 5 holding the tapered rollers 4 at prescribed intervals in the circumferential direction. (a circumferential length on a PCD) - (roller diameter×roller quantity) is set less than roller diameter. COPYRIGHT: (C)2006,JPO&NCIPI
