ABSTRACT:
A cage has a pair of annular bodies and a plurality of columns provided at equal spacings to couple the annular bodies together to receive spherical rollers therebetween. The columns have side faces each having both axial end portions thereof formed by a composite surface having a flat surface provided outside the pitch circle of the spherical rollers and a conical surface provided inside the pitch circle. Each flat surface is inclined with respect to a plane including the axis of each spherical roller and the axis of the cage so as to come into point-to-point contact with the outer periphery of the respective spherical roller while the bearing is rotating. Each flat surface intersects each plane including the abovementioned axes along a line intersecting the axis of each spherical roller at a right angle.
