Abstract: A tensioner with a base assembly, an arm member movably mounted to the base assembly, first and second pulleys mounted to the base assembly and the arm member, respectively, a tensioning spring and a damper. The base assembly has a base structure and a bearing that permit the base structure to pivot about a drive axis. The tensioning spring is disposed in a load path between the base assembly and the arm member and biases the second pulley toward the first pulley in a manner that is configured to tension a belt. The damper is coupled to the base assembly and the arm member and damps motion of the arm member when the arm member moves relative to the base assembly.
