    摘要: A retainer for a roller bearing includes a pair of annular portions and a plurality of columns 23 provided between the annular portions. A plurality of pockets are defined by the annular portion and the column each for receiving a roller. An indented relief is provided on the corners of the plurality of pockets and the circumferential average width d (mm) of the column at the area where the indented relief is provided, the axial thickness t (mm) of the annular portion at the area where the indented relief is provided, the radius r (mm) of curvature of the indented relief, the average diameter Da (mm) of the roller and the pitch circle diameter dm (mm) of the bearing satisfy a relationship: 0.07×dm+20≦(2/d+4/t+1/r)×Da≦0.07×dm+50.

    摘要: A seal member with its base end connected to a metal core has three seal lips. The thickness of the tip end of the intermediate seal lip in the intermediate position is d1, and the thickness of the base end is d2. The thickness of the tip end of the innermost inner seal lip is D1 and that thickness of the base end is D2. In this case, at least part of the base end of the intermediate seal lip and inner seal lip has its thickness regulated to be 0.2·d1≦d2≦0.8·d1, and 0.5·D1≦D2

    摘要: A split bearing ring according to the invention includes two or more split portions into which the split bearing ring is divided with respect to a circumferential direction. Surfaces of the split portions other than circumferential end faces of the spit portions have hardness of HRC 59 or higher, the surfaces of the split portions other than the circumferential end faces are quenched and tempered, and the surfaces of the split portions other than the circumferential end faces have a prior austenite grain size of No. 6 or above. The split portions are formed by applying a load to a bearing ring such that stress generated on one end side of the bearing ring with respect to an axial direction is larger than stress generated on the other end side of the bearing ring with respect to the axial direction.
