Abstract

L'invention concerne un dispositif de commande d'un mécanisme de traction pour moteurs à combustion interne, comprenant un rouleau tendeur et/ou déflecteur (1) qui présente deux roulements à billes identiques, à rainure unique (2, 2'), axialement en contact entre eux, et qui peut être complété par pulvérisation cylindrique de matière plastique. En vue de réduire le coût du rouleau (1), les deux roulements à billes à rainure unique (2, 2') sont réalisés sans joint d'étanchéité du roulement (6, 6') sur leurs faces de contact (3, 3').
