A cage (14) for a split roller bearing (10) is composed of two semi-circular components (15) detachably interconnected at their ends. Each of the components (15) is itself constricted from a pair of blanks (17). Each blank (17) takes the form of a mild steel pressing with a continuous semicircular wall portion (18) with spaced-apart projections (19, 20) at the sides. The projections (19, 20) are bent along fold lines (L, M) so that the wall portions (18) form the sides (24) of the cage and some of the projections (20) overlap at a centre region (30) of the cage and are fixed together. The rollers (11) are located in pockets (40) between side edges of the projections (19, 20).

L'invention porte sur une cage (14) de roulement à rouleaux (10) en deux pièces, faite de deux éléments (15) semicirculaires réversiblement liés par leurs extrémités. Chacun des éléments (15) est obtenu à partir d'une paire d'ébauches (17) d'acier doux découpées à la presse présentant une partie paroi semicirculaire (18) continue et des saillies espacées disposées sur ses côtés. Les saillies (19, 20) sont repliées le long de lignes de pliage (L, M) de manière à ce que la partie paroi forme les côtés (24) de la cage et que certaines des saillies (20) recouvrent la zone centrale de la cage et soient fixées ensemble. Les rouleaux (11) sont placés dans des alvéoles (40) entre les bords latéraux des saillies (19, 20).
