ABSTRACT:
The invention is an improved tensioner for tensioning a power transmission belt. It is of the type having a pulley adapted to communicate with a surface of a power transmission belt, an arm supporting the pulley upon which the pulley is rotatably mounted via a pulley bearing, and having a shaft supporting the arm. The shaft is rotatably supported by a pivot bearing. Further, it is of the type having an attachment point for a strut with the strut attached to the attachment point. It is improved by the pulley and the attachment point being laterally offset in relation to the pivot bearing and substantially balanced in terms of parasitic torque across the pivot bearing.
