Heavy duty engines were often shipped with pulleys made of cast iron which are prone to corrosion. On older engines the casting patterns for the pulleys specific to those engines have often been lost to wear and tear, damage or company ownership changes.
Airflow Systems offers pulleys machined from appropriate alloy billets. They are inherently balanced and typically require little or no special tooling charges. These pulleys have been successfully used in harsh environments and offer a smooth finish that retards corrosion. Send us your requirements in quantities of 20 to 1000.
