C93200 Bronze Bushing

Our Bronze Bushings are machined from continuous cast C93200 (SAE 660) bronze for superior quality and performance. The continuous casting process assures a uniform bronze structure throughout the bearing, free from porosity and hard particle inclusions commonly found in other cast processes.

C93200 bronze is a type of bearing bronze that contains a high percentage of tin, which gives it excellent wear resistance and good corrosion resistance. It is commonly used in applications such as bushings, bearings, and thrust washers. These standards provide off-the-shelf economy for most applications and may be easily resized, oil-grooved, or graphite to meet special requirements.

Description

C93200 (SAE660 RG7) is considered lead-tin bronze for the “standard” type bearing material. The alloy has excellent processing properties, good hardness, strength and wear resistance, and excellent wear resistance. Typical applications include bearings, washers, bushings, auto parts, spindle bearings, machine tool bearings, crane bearings, trunnion bearings, roll neck bearings, rolling mill bearings, fuel pump bushings, water pump bushings, diesel engine piston pin bushings, forging elbows Section rod bearings, stuffing box hydraulic presses, hydraulic press main linings, pump impellers, general purpose bushings, pipe fittings, pump units, spherical bearings, etc.

Some of the benefits of C93200 bronze bushings include:

  • Excellent wear resistance
  • Good corrosion resistance
  • High strength and durability
  • Good machinability
  • Good thermal conductivity
  • C93200 bronze bushings are typically manufactured using casting or machining processes, and they can be customized to meet specific application requirements.

Graphite Embedded C93200 Bronze

Graphite embedded C93200 bronze bushing, also known as “Graphite Bronze Bushing,” is a bronze alloy with graphite particles evenly distributed throughout its structure.

The addition of graphite to the bronze matrix provides several benefits, including improved lubrication and wear resistance. The graphite particles act as a solid lubricant, reducing friction between the bronze surfaces and increasing their resistance to wear and tear. This makes graphite bronze ideal for applications involving sliding or rotating parts, such as bushings, bearings, and gears.

In addition to its superior lubrication and wear resistance properties, graphite bronze also exhibits excellent corrosion resistance and high thermal conductivity. This makes it an excellent choice for use in harsh environments and applications where heat dissipation is important.

Overall, graphite-embedded C93200 bronze is a versatile material that offers a combination of properties that make it well-suited for a variety of applications in the mechanical and engineering fields.
