C93700 High Leaded Tin Bronze "80-10-10" (Bearing Bronze)

C93700 has excellent machining properties, medium strength and good corrosion resistance and will withstand mild acids as found in mine water. Bearings manufactured from C93700 have excellent wear resistance under conditions of high speed, heavy pressure and vibration, have low friction and can be used where lubrication is less than adequate and there may be minor misalignment. C93700 bearings require a hardened shaft and maximum shaft surface speeds of 4 m/sec can be tolerated.
