C93200 (SAE 660) Bearing Bronze is considered the standard bearing material for light duty applications. While it is easily machined, the bronze alloy is hard, strong and resistant to wear. It also conforms well to journal irregularities and is less dependent on lubrication than other alloys. The alloy has reasonable corrosion resistance to seawater and brine.
