Abstract: A drawn cup roller bearing includes: an outer ring including a raceway surface; a first rib formed at one end of the outer ring by being bent substantially perpendicular to the raceway surface; a second rib formed at the other end of the outer ring by being bent inwardly so as to be substantially parallel to the raceway surface; a cage including pockets for holding rollers, respectively; and an annular projection stopper which is projected radially outwardly and provided over an entire outer circumference at a pocket side position of an outer circumferential surface of the cage. An end surface of the cage abuts against a part of the first rib and the annular projection stopper is interposed between an end surface of the second rib and the rollers in a state that the cage is assembled into the outer ring.

Abstract: Quenching heat treatment is performed on a whole rocker arm bearing assembly in which shaft ends of a supporting shaft are fixed to inner peripheral edges of shaft end insertion holes of a pair of opposite sidewalls, and by the outer ring is rotatably supported on a raceway portion of an shaft intermediate portion of the supporting shaft through a plurality of rolling elements or directly, thereby manufacturing a rocker arm bearing apparatus.

Abstract: There is provided a rolling slide member coming in contact with a mating member in a rolling or sliding manner, wherein a plurality of grooves having an inclination of 0 to 30 degree and a groove depth of 0.5 to 15 ?m are formed in a circumferential direction at the time of grinding a contact surface with the mating member. In the contact surface, the axial surface waviness is set to 0.1 or more in the filtered centerline waviness (WCA) and the axial surface roughness is set to 0.7 or more in the ten-point height of roughness profile (Rz) by the grooves 26.

Abstract: There is provided a rolling slide member coming in tact with a mating member in a rolling or sliding manner, rein a plurality of grooves having an inclination of 0 to 30 degree and a groove depth of 0.5 to 15 ?m are formed in a circumferential direction at the time of grinding a contact face with the mating member. In the contact surface, the axial surface waviness is set to 0.1 or more in the filtered centerline waviness (WCA) and the axial surface roughness is set to 0.7 or more in the ten-point height of roughness profile (Rz) by the grooves 26.
