IDLER OR ROLLER DEVICE

摘要

A tension roller or reel device for a torque transmission element. The device comprises at least one bearing having one inner race, one outer race and at least one row of rolling elements between the inner race and the outer race, a pulley on top of the outer race, and a retaining screw inserted into a central bore of the inner race. The bore of the inner race is provided with a circumferential cavity in which a retaining ring is fitted securely and integrally, the retaining ring comprising an interaction feature providing interaction with the screw so as to allow an axial immobilization of the screw in relation to the bearing.
