Bunting cast bronze bearings 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 900 sizes, these standards provide off-the-shelf economy for most applications, and may be easily resized, oil grooved, or graphited to meet special requirements.
