C93200 is Your Wear Solution

C93200 Bearing Bronze is an all-purpose alloy for bearings, bushings, and washers. It is also known as SAE 660, SAE 660 bronze, or SAE 660 bearing bronze. Its strength, wear resistance, and anti-friction properties make it an excellent solution for wear applications.    

One of C93200 Bearing Bronze’s most remarkable qualities is its long-life span. In addition to the lead in the alloy allowing it to be less dependent on lubrication. These are some of the attributes that makes it a superior alloy for bushing and bearing applications.

C93200 Bearing Bronze has good strength, wear resistance, and anti-friction properties. It also has good machinability and good load carrying ability.

Physical properties of C93200 Bearing Bronze include:

  • 35,000 psi Minimum Tensile Strength
  • 20,000 psi Minimum Yield Strength
  • 10% Minimum Elongation (in 2”)
  • 55 – 65 Brinell Hardness

C93200 Bearing Bronze is typically utilized in industrial settings for a variety of applications including, but not limited to: thrust washers, pumps, bushings, machine parts, main spindle bearings, machine tool bearings, trunion bearings, roll neck bearings, bearings for cranes, rolling mill bearings, linkage bushings for presses, fuel pump bushings, water pump bushings, diesel engine wrist pin bushings, pump fixtures, insert bearings, hydraulic press main lining, hydraulic press stuffing box, forging press toggle lever bearings, and pump impellers.
