Shoulderless roller bearing

摘要

A cage for the rollers of a journal bearing, held between two shoulderless track surfaces at least one of which is formed by a ring, has an annular flange resiliently engaging in a peripheral V-groove of the ring which is axially offset from the roller-holding cage pockets. The flange has an end face formed with an annular incision designed to make it radially compressible, that incision lying at or just beyond one of the radial limits of the gap formed between the two track surfaces. The axially outer boundary of the V-groove is recessed with reference to the associated track surface.
