  • C86300 (CuZn24Al6Fe3Mn4)  Manganese Bronze, Wear resistance, excellent wear resistance. It’s suitable for high load, low-speed working conditions

  • C95400 (CuAl11Fe4) Aluminum Bronze, It Can Be Strengthened By Heat Treatment, Its Strength Is Higher Than Tin Bronze, And Its Resistance To High-Temperature Oxidation Is Better.

  • 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.

Bronze vs. Plastic Bushings, What is the difference?

Affordable and versatile, the plastic bushing is fast and cost-effective.
With all the benefits of plastic, where does that leave metal? Bronze remains a popular choice for bushings because it’s available in so many alloys and compositions, expanding its reach into even more applications. bronze bushing material is harder and less likely to break or deform than those made of other materials. bronze bushings are long-lasting and corrosion resistant. their strength allows them to hold up under impact. Moreover, bronzeoilless.com bronze bearings combine a copper matrix with a graphite solid lubricant, eliminating the need for additional oiling and making them self-lubricating and maintenance-free.

C86300 Bronze Bushing

C86300 Manganese Bronze (SAE 430B) is a high-strength alloy used for bushings, bearings, gears, hooks, tightening nuts, bridge pins, bridge plates, valve stems, and hydraulic cylinder parts.

Manganese bronze bushing is typically used for heavy-duty applications. It performs best at low speeds and is reliably lubricated. It is suitable for use in steel mill equipment, the wood pulp industry, marine applications, and earth-moving machinery. Larger rings and tubes can be centrifugally cast or sand cast.

Leaded Tin Bronze Alloys

These alloys are usually more readily available and less expensive than other bronze alloys.
High-lead tin bronze alloys contain between 7% and 30% lead. Due to the presence of lead, this combination is easy to cut and maintains good thermal conductivity and good lubricity. High lead-tin bronze is well suited for bearing applications where lubrication boundaries may be lost. These alloys perform well in harsh environments where foreign materials, such as dirt and other foreign substances, may be present. Because of their ductility, they can encapsulate foreign material and protect the wear surfaces of coupled parts in the process.
C93700 is required for applications where acid resistance to sulfite fluids is required, bearing plates, bearings, bushings, high speed and heavy pressure bushings, corrosion resistant castings, crankshafts, high speed/heavy duty bearings, impellers, machine parts, steel mill repair parts, pressure-resistant castings, pumps, steel mill slides

The benefits of oilless bronze bearings

Why Use Bronze Bushing?

Bronze bushing is a part of mechanical equipment, first of all, its wear resistance is relatively good, and different bronze bushing materials have different characteristics of the equipment.
Secondly, the bronze bushing material is very resistant to corrosion, and it is mainly used in the atmosphere and fresh water. In the process of use, it is generally not easy to appear in the situation of bite. Even in the absence of lubricants and water lubricants can still carry out normal work, and sliding and self-lubricating properties can still be maintained.
Finally, the pressure resistance is also relatively good, and can well withstand the bearing side pressure, in the case of high load pressure copper bushings can also be operated. Its casting performance and cutting performance are also relatively good. So the bronze bushing is still a good accessory.
