    Abstract: A tapered roller bearing is capable of suppressing the occurrence of fretting without shortening its fatigue life. The tapered roller bearing includes an outer race, an inner race, a plurality of taper rollers interposed between the outer race and the inner race, and a retainer for retaining the tapered rollers. The tapered roller bearing is used in an idler portion of an automobile transmission, which is interchanged between an idle state in which the outer race idles with respect to the inner race and a shift state in which the outer race and the inner race are rotated synchronously with each other. A ratio of α/β≧4.9 is established on a premise that an outer-race raceway surface angle is 2α and a roller angle is β.

    Abstract: A sealed rolling bearing includes an inner ring and an outer ring defining a bearing space therebetween. Axially inner and outer contact seals are provided on each side of the bearing space to seal the bearing space. The axially outer contact seals stop any splashed muddy water, thereby keeping the lips of the axially inner contact seals and their sliding contact surfaces free of muddy water. This prevents the lips of the axially inner contact seals and their sliding contact surfaces from becoming worn by muddy water. The axially inner contact seals thus maintain high sealability even if the bearing is used in environments where muddy water splashes.

    Abstract: A tapered roller bearing and an automotive gear shaft support device which can ensure a long endurance life even in the state in which debris is mixed. On the surfaces of an outer ring, inner ring, and tapered rollers formed from carburized bearing steel having an oxygen content of 9 ppm or less, carbo-nitrided layers having a carbon content of 0.80 wt % or over, a Rockwell hardness HRC of 58 or over, and a residual austenite content of 25-35 vol % are formed to increase mechanical properties and fatigue characteristics of the parts and to stably maintain the carbo-nitrided layers on the surfaces of the parts to a quality having suitable toughness, thereby markedly improving the endurance life of the tapered roller bearing in a state in which debris mixed.
