C93200 Bronze Bushing

Our Bronze Bushings are machined from continuous cast C93200 (SAE 660) bronze for superior quality and performance. The continuous casting process assures a uniform bronze structure throughout the bearing, free from porosity and hard particle inclusions commonly found in other cast processes.

Our standard bearing line features over 1,000 sizes that are carried in stock. These standards provide off-the-shelf economy for most applications and may be easily resized, oil grooved, or graphited to meet special requirements.
