    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: 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.
