500 Series Driven Unit

Model 500 Series
The model 500 drive and driven variable pulleys are installed in a power train drive system to better match output requirements with an engine output. If the engine is allowed to run at its peak output power, the most power available from the engine will be directed to the driven shaft. The model 500 responds to load requirements and changes the ratio between the drive and driven pulleys so that the engine can maintain its peak power output.
