A tensioner comprising a base, an arm pivotally engaged with the base, a pulley journalled to the arm, a spring disposed between the base and the arm, a damping member having an inwardly oriented damping band surface with respect to an axis of rotation (R-R). The damping band surface frictionally engaged with the arm, and having an end ( 32 ) connected to the base and another end ( 31 ). The damping member disposed radially inward of the spring with respect to an axis of rotation (R-R), and the other end ( 31 ) of the damping member is disposed between the spring and the arm. The other end ( 31 ) transmits a substantially radial spring force (SF 2 ) with respect to an axis of rotation (R-R) from the spring to the damping band surface.
