    摘要: A cam follower with roller of the present invention includes a cam follower body having a roller supporting portion integrated therein, a roller supporting shaft having both ends fixed to the roller supporting portion and a roller rotatably supported on the roller supporting shaft with a plurality of needle rollers interposed. At least one of the supporting shaft and the needle roller has a nitride layer on the surface thereof, and has a surface hardness of at least HV 650 and an amount of retained austenite of at least 25% by volume and at most 50% by volume. Thus, a cam follower with roller having excellent durability and fatigue life can be obtained.
