    摘要： A ball bearing with double raceway rotatably supports a pinion shaft having a pinion gear on its one end. This ball bearing with double raceway is provided with: an outer ring member having a large-diameter raceway surface and a small-diameter raceway surface; an inner ring member having a large-diameter raceway surface and a small-diameter raceway surface that correspond to the large-diameter raceway surface and the small-diameter raceway surface of the outer ring member; a large-diameter-side row of balls that are interpolated between the two large-diameter raceway surfaces; a small-diameter-side row of balls that are interpolated between the two small-diameter raceway surfaces; a large-diameter-side cage that holds the large-diameter-side row of balls; and a small-diameter-side cage that holds the small-diameter-side row of balls. In this ball bearing with double raceway, the row of balls on the anti-pinion gear side of the two rows of balls is subjected to a load prior to the row of balls on the pinion gear side.

    摘要： There are provided an inner ring having a first raceway at an outer periphery thereof, an outer ring having a second raceway at an inner periphery thereof, an intermediate ring which is interposed between these, and has a third raceway at an inner periphery thereof and also has a fourth raceway at an outer periphery thereof, first rolling elements interposed between the first raceway and the third raceway, and second rolling elements interposed between the fourth raceway and the second raceway. The intermediate ring includes a larger-diameter ring portion, and a smaller-diameter ring portion formed on the larger-diameter ring portion through an inclined ring portion. The third raceway is formed at a boundary portion between the larger-diameter ring portion and the inclined ring portion, and the fourth raceway is formed at a boundary portion between the smaller-diameter ring portion and the inclined ring portion.
