Abstract
Abstract The process comprises placing on the journal the roller provided with its needles and the annular member for axially retaining the needles. Thereafter, one end of an elastically yieldable ring is engaged in a passageway provided on the journal and the ring is shifted along this passageway until it is completely received in a groove. This method is much more reliable and lends itself to a thorough automatization.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
139 words
In an assembly comprising a journal, a roller rotatively mounted on the journal, rolling elements interposed between the journal and the roller and axially retained between means defining an annular radial support surface on the journal and an annular member in the vicinity of a free end of the journal, which annular member is held in position by an elastically yieldable split ring which is planar in the free state and trapped between the annular member and a groove in the journal the improvement comprising a passageway which is provided in the journal between the free end of the journal and said groove and is connected to said groove and has a substantially helical shape and a depth which is such that it defines with the adjacent annular member a gap permitting the insertion of the elastically yieldable ring.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
15 words
An assembly as claimed in claim 1, wherein the passageway has a roughly semi-circular section.
Claim 4
Dependent Claim
28 words
