CAST BRONZE MACHINED SAE 430B, CuZn25Al5Mn4Fe3-C (SAE-430)

Engineered for a Longer More Reliable Service Life, Metric bronze bushing.

Graphite Manganese Bronze bushings, also known as brass graphite bearings, are special self-lubricating bearings designed for different applications and working conditions. A key type of these bearings, solid inlaid copper graphite bearings (JDB), combines the advantages of metal bearings and oil-free lubrication. The metal base supports the load, while a specially formulated solid lubricant reduces friction. These bearings offer high load capacity, impact resistance, high-temperature tolerance, and strong self-lubrication, making them ideal for heavy loads, low speeds, and reciprocating or oscillating movements—even in conditions where lubrication and oil film formation are challenging. They also resist water and corrosive substances. Current applications include metallurgical continuous casting machines, rolling equipment, mining machinery, ships, steam turbines, water turbines, injection molding machines, and production lines.

We manufacture graphite oilless bushings, self-lubricating bushes, graphite-impregnated bronze bushes, oilless bushes, Manganese Bronze bushings with graphite plugs, and both metric and inch-size oilless bushes.

High-strength C86300 manganese bronze grooved bushings, Manganese Bronze C86300 bearings, and manganese bronze bushings with graphite plugs. Additional offerings include C86300 manganese bronze flange bearings, oilless bearings, oilless brass flange bushings, and graphite-plugged bearings.

Why is Manganese Bronze Bushing? (Manganese Bronze Bushings = oilless Bushing)

Manganese Bronze Bushings are a kind of product with self-lubricating properties.

Appropriate size holes are developed and well-arranged on the friction surface of copper-Manganese Bronze Bushings as a metal matrix, and graphite or molybdenum disulfide are embedded as a solid lubricant.

This combination leverages the performance advantages of both metal alloys and non-metallic friction-reducing materials, retaining the metal’s high load-bearing capacity and the anti-wear material’s lubricating property.

So Manganese Bronze Bushings are especially suitable for the environment like no refueling, less refueling, high temperature, high load, and water environment.

Application of Manganese Bronze Bushings :

● It is difficult to form lubricating oil film under low speed and heavy load.

● Bad environment, limited structure, not easy to add lubricating oil.

● The large temperature difference in the working environment.

● The maintenance is difficult and the long life of the bearing is required.

● When used in corrosive media.

● When impact load is easy to occur.
