    Abstract: The invention provides a cam follower having an outer ring which is used in a state where the cam follower comes into sliding contact or rolling contact with a mating part. The outer ring is configured such that the hardness of a surface layer portion existing between the surface and at least 3 μm below the surface is Hv 780 to 900, and the hardness of an internal surface portion existing at a depth of 10 μm or more from the surface is lower than the hardness of the surface layer portion and less than Hv 780. Such hardness can be obtained by performing soft shot blasting or flow barrel processing on a surface layer portion of a base material to be the outer ring.

    Abstract translation: 本发明提供了一种具有外环的凸轮从动件，该凸轮从动件在凸轮从动件与配合部件滑动接触或滚动接触的状态下使用。 外圈的结构使得存在于表面之间的至少3μm之间的表面层部分的硬度为780至900，并且内表面部分的硬度存在于10μm或更大的深度 该表面低于表面层部分的硬度并且小于Hv780。这样的硬度可以通过对作为外圈的基材的表面层部分进行软喷丸处理或流动桶加工来获得。

    Abstract: The bearing devices includes a pair of opposed sidewalls, a supporting shaft which is inserted into shaft end insertion holes provided in the both opposed sidewalls, and a roller supported between the both opposed sidewalls by the supporting shaft. The supporting shaft includes a shaft main body that is made of a steel product subjected to a heating process and has a step shape in which the outer diameters of the both shaft ends are smaller than that of a middle portion and caps which is fitted to the both shaft ends and of which the end can be caulked. An end outer-diameter side edge of the cap is caulked to an inner-diameter side edge of the insertion hole.

    Abstract: A bearing apparatus includes: two split outer ring halves which are mounted to the housing; a plurality of rolling elements which are provided so as to roll on the two split outer ring halves; and a cage which holds the rolling elements such that the rolling elements are disposed at substantially equal intervals in a circumferential direction of the cage and which is split at a position of the cage to form joint surfaces, an outside diameter of the cage being guided by inner circumferential surfaces of the split outer ring halves. An outside diametrical dimension in a normal direction to the joint surfaces is made larger than an outside diametrical dimension of the cage in a direction parallel to the joint surface, and vicinity of an outside diametrical position of the cage lying in the normal direction is made to be guided by the outer ring halves.
