Cage e.g. plastic cage, for e.g. rolling element bearings, for guiding rollers, has rings comprising deformation region adjacent sides of intermediate region in direction, where plastic deformation is carried out by deformation region

摘要

The cage (5) has cage rings (8a) changed from output diameter (D) into final diameter by a plastic deformation. The cage rings comprise a deformation region (9) i.e. bending zone, in a rotation direction, where the region is provided adjacent to two sides of an intermediate region (10) in a circumferential direction. The plastic deformation is carried out by the deformation region. A pocket (6) is designed as a sacrificial pocket of the deformation region. Width of the pocket in the rotation direction is different from width of another pocket by the plastic deformation. The deformation region is designed as a tumbling, a seam (11) and a bend. Independent claims are also included for the following: (1) a set comprising cage (2) a method for manufacturing a cage.
