C93200 Bearing Bronze

C93200 Bearing Bronze

Bronze Bars C93200 (SAE 660) are high quality smooth machine finish stock for general utility bearings and bushings and which are highly resistant to impact, wear and corrosion. It is a general purpose bearing alloy possessing good anti-friction properties, ample strength and hardness, adequate ductility and excellent machinability. It is used as bearings, bushings, light duty gears and sprockets, impellers, wear strips, plates, automotive fittings and washers. It is used extensively in pumps, cylinders, machine tools, earth moving machinery and a myriad of general purpose applications.
