Abstract
A pulley device for supporting a belt of a chain tensioning idler or a runner roller includes a bearing having an outer ring mounted for rotation relative to a coaxial inner ring and first and second C-shaped pulley parts mounted on the radially outer surface of the outer ring with their openings facing each other. The radially outer portion of the first and/or second pulley part includes at least one radial through opening, and a first portion of at least one of the pulley parts radially inward of the through opening is deformable from a first configuration in which the first pulley part is axially movable relative to the outer ring to a second configuration in which the first pulley part forms an interference fit with the outer ring or with the second pulley part. Also a method of connecting the pulley parts to the outer ring.
