An inner damping member (20) is axially engaged with an outer housing. The outer housing (10) is connectable to a tensioner arm (11). A wegde member (30) connected to an immoveable mounting member (40) is axially engaged with an inner portion of the inner damping member. The outer housing is axially moveable relative to the wedge member. A spring (50) bears upon and urges the outer housing away from an end cap (60). The end cap comprises a rod (70), which extends axially within the wedge member and has an end connected to the inner damping member. The rod transmits a spring load force from the end cap to the inner damping member such that the inner damping member radially expands against the outer housing in response to the spring load force, thereby creating a frictional force between the inner damping member and the outer housing which damps an outer housing movement in proportion to the spring force.
