The Oil-Less C86300 Manganese Bronze Bushing SAE 430B is a unique type of bushing designed specifically for applications requiring high wear resistance and self-lubricating properties, especially for plate components.

Constructed from C86300 alloy, this manganese bronze bushing incorporates SAE 430B specifications, ensuring it meets strict industry standards for performance and durability. The alloy's composition, including copper, zinc, aluminum, manganese, and iron, provides excellent mechanical properties such as strength, ductility, and corrosion resistance.

The key feature of this bushing is its oil-less and self-lubricating design. Embedded graphite particles within the bushing material act as natural lubricants, reducing friction and wear between the bushing and mating surfaces. This eliminates the need for external lubricants, simplifying maintenance and reducing operational costs.

For plate applications, the Oil-Less C86300 Manganese Bronze Bushing SAE 430B offers a reliable and long-lasting solution. Whether used in plastic molding, metalworking, or other industries, these bushings ensure smooth and precise movement of plates and components, improving overall machine performance and productivity.

In summary, the Oil-Less C86300 Manganese Bronze Bushing SAE 430B is a high-performance bushing designed for plate applications requiring superior wear resistance and self-lubricating properties. Its unique alloy composition and innovative design make it a reliable choice for a wide range of industrial applications.

Self-Lubricating Oil-Less Type Bushings

Material technical Data

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.

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
