ASTM B271 Alloy Graphite Plugged Bushings, specifically the C86300 type, with dimensions of 400 x 470 x 750 mm, refer to metal-based self-lubricating bearings that utilize a graphite-based material for lubrication. These bushings are designed to provide long-lasting, maintenance-free operation in a wide range of industrial applications.

ASTM B271 is a standard specification that covers centrifugally cast, bronze-based, graphite-lubricated bearings intended for use in applications requiring high wear resistance and low friction. The C86300 alloy is a type of tin-based bronze that contains graphite particles embedded within the metal matrix. These graphite particles provide the self-lubricating properties that allow the bearing to operate without the need for external lubricants.

The dimensions of 400 x 470 x 750 mm refer to the outer dimensions of the bushing, which is typically installed into a housing or frame to provide a sliding surface for a rotating or reciprocating shaft. The metal base of the bearing provides structural support, while the graphite-lubricated layer reduces friction and wear between the bearing and the shaft.

Overall, ASTM B271 Alloy Graphite Plugged Bushings with C86300 alloy and the specified dimensions offer a reliable, maintenance-free solution for industrial bearing applications requiring high wear resistance and low friction.

Applications for C86300 Manganese Bronze Bearings

The C86300 Bronze bushings is used in a variety of applications. Typical uses for this alloy are: Extra heavy duty, high strength alloy. Large valve stems bushing, gears bearing, cams bushes, slow-speed heavy-load bearings, hydraulic cylinder bushingparts.

Bronze can operate at high speeds under heavy loads, but require high shaft hardness and nonabrasive operating conditions. This alloy has excellent mechanical qualities and good corrosion resistance. This alloy is compromised of copper, manganese, aluminum and iron. This combination raises the tensile strength.

Self-Lubricating Oil-Less Type Bushings

Engineered for a Longer More Reliable Service Life

Graphited bearings should be soaked in lubricant prior to application. The graphite absorbs the lubricant, which is then transferred to the shaft when heated by the shaft motion. This action provides oil needed to lubricate but not in sufficient quantity to cause leakage at the bearing ends. The oil is re-absorbed by the graphite when motion ceases.

Plug graphiting is accomplished by drilling a rowed, staggered hole configuration through the bearing wall and pressing graphite into these holes and hard baking. The size and number of drilled holes and the number of rows is determined by the bearing length and diameter.

Solid self-lubricating bearing with graphite plug insert | Graphite copper sleeve bushings

Graphite Plugged Bronze Bushings are all self-lubricating and maintenance free. These bushings are machined out of continuous cast bronze and plugged with solid lubricant plugs. A bushing and it's mating surface should always be seperated by a film of lubricant.Many of VIIPLUS’s components use graphite. Here is what you need to know about it. Graphite is ordinary carbon in a highly unusual form, a two-dimensional crystal. Think of it as a one-atom thick sheet. A piece of graphite is a stack-up of these sheets. A graphite pencil lead feels oily because these one-atom thick sheets are very slippery.

Performance

Graphite Plugged Cast Bronze Bushings can be utilized where heavy loads must be supported at low to medium speeds

The Plug Graphite Cast Bronze Bushing is able to withstand high temperatures up to 570 F

The self-lubricating feature allows bearings to be used where oiling is difficult, expensive to implement, and where grease/oil cannot be used. Excellent lubrication is achieved even under high loads at low speeds.

Self lubrication with specially embedded solid lubricants reduces friction. Coefficient of Friction: 0.04 to 0.2
