Abstract
A centrifugal actuator is provided for a centrifugal clutch having an axially fixed base and an axially movable pulley flange. The actuator includes a drive arm having a camming surface and a bottom that is pivotably attached to the movable pulley flange, a mounting pin coupled to the fixed base, and an improved roller that rotates about the mounting pin. The roller includes an outer sleeve and an inner sleeve coupled to the outer sleeve. The outer sleeve is made of metal and has an outer surface that frictionally engages the camming surface of the drive arm. The inner sleeve is made of a plastics material and has an inner load-bearing surface that engages the mounting pin. The roller rotates about the mounting pin as the drive arm swings outwardly and inwardly.
