Abstract

A pulley assembly for belt tensioners having a bearing unit provided with a rotating outer ring and made of metal, an outer wheel body overmoulded onto the outer ring to rotate with the outer ring and interact with a belt, a gripping surface at the interface between the outer wheel body and the outer ring to prevent circumferential slipping between the outer wheel body and the outer ring; and an axial retainer integral with the outer ring and having two lateral edge members located axially on opposite sides of the gripping surface to engage the outer wheel body and prevent axial movement of the outer wheel body relative to the outer ring.
