Self-Lubricating Bronze

OVERVIEW

CDA 938 SAE 67 Bronze alloy is the true self-lubricating bronze due to its high lead content 15% Pb which does not require any external lubrication. High lead bronze alloy can absorb dirt and grit without the risk of damaging the shaft. It has very low coefficient of friction between shaft and bushing thus perfect for high-speed applications that subject bushing to high local heat. Highly recommended for hard-to-lubricate bronze bushing

TYPICAL USES

Light-duty bronze bushing, High speed bushing with minor load, Turbocharger bushing

APPLICATION

Light Load | Medium Pressure | High Speed
