A tensioner for tensioning a belt includes a support housing at least in part defining a spring cavity. A damping member having a first friction bearing surface is at least partially disposed in the spring cavity. An arm pivotally attached to the support housing has a second friction bearing surface. A spring is located in the spring cavity and operatively connected to the arm and damping member to pivot the damping member about a pivot location such that the first friction bearing surface of the damping member is biased against the second friction bearing surface of the arm to dampen relative movement between the arm and the support housing.
