Abstract:
Cam actuated systems, such as valve trains for an engine, typically bring cam lobe action to the engine valve via a linkage that includes a cam actuated roller assembly which may be either a rocker or a lifter. These cam actuated rocker assemblies include a housing with a pair of arms with roller support bores there through. A roller support pin is received in the roller support bores, and rotationally supports a roller mounted about the roller pin and between the arms of the housing. The roller pin may include a relatively hard and inexpensive core, such as steel, cladded with a relatively soft more expensive metal, such as bronze.
