These products are manufactured from continuous cast bronze material that conforms to specifications ASTMB 505-C932, SAE 660 and CuSn7ZnPb. Our cast bronze standards are general-purpose bearings that provide the best mix of functional properties, availability and economical cost. They offer excellent load carrying capabilities with good anti-frictional properties. They can perform over a broad range of temperatures and can readily be modified with grease grooves, oil grooves or self-lubricating graphite plugs. All standard stock sizes are also available in other materials such as no-lead bronze, aluminum bronze, manganese bronze and cast iron.
