ABSTRACT:
A cage and roller type roller bearing is provided. The bearing generally include a cylindrical cage and a plurality of rollers which are maintained in position by the cage. The cage includes a pair of circumferential sections and a plurality of axial sections extending between the pair of circumferential sections and spaced apart at a predetermined pitch in the circumferential direction to thereby define a plurality of windows each receiving therein a corresponding roller rotatably and generally rectangular in shape and somewhat larger in size than the roller. Each of the axial sections has its central inner portion of its inner surface removed to define an inner recess so that the axial section is divided into a relatively thin central portion and a pair of relatively thick end portions. In the preferred embodiment, the relatively thick end portion is calked to define a pair of inner and outer roller holding projections and a pair of inner and outer grooves at the inner and outer peripheral surfaces thereof, respectively. These inner and outer roller holding projections defined by calking serve to prevent the roller from slipping away from the corresponding window, and the inner and outer grooves serve as oil pockets for reserving a quantity of lubricant therein.
