WIPO Patent Application WO/2011/142240
Kind Code:

Abstract:
Outer ring pieces for a split needle bearing can be stably affixed to objects, such as a bearing support section and a cap, to which the outer ring pieces are to be mounted, the affixation being performed without working the objects. Also, the outer ring can be subjected to a thrust force without using an independent part. Outer ring pieces (16) which compose the outer ring (12) of a split needle bearing (11) are press-formed products. Outer ring piece flanges (18) are formed along the entire circumferences of both ends of the outer ring pieces (16). Means for affixing the outer ring pieces (16) to objects to which the outer ring pieces are to be mounted are provided to the outer ring pieces (16). When the outer ring pieces (16) are assembled together, outer ring flanges (24) are formed along the entire circumferences of both ends of the outer ring (12).
