Product Description

Manganese Bronze  with Graphite Plugs

C86300 (SAE 430B) Manganese Bronze Bushings 
C86300 Manganese Bronze (SAE 430B) is a high strength alloy used as bushings, bearings, gears, gibs, screw down nuts, bridge pins, valve stems and hydraulic cylinder parts.


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.


Typical Aplications:

Advantages of Slide Elements:

※ Maintenance free
※ Wear resistant
※ Low frictional resistance
※ Resistant against temperatures up to
approx. 300℃ (approx.572oF)
※ No impurity through discharge of lubrication
※ Environmentally friendly
※ Corrosion resistant
※ Insensitive to impact stress
※ Specially suited for oscillating slide motions
※ Stick, slip free sliding
※ Long life
※ Automotive industry-tool support, die
※ Injection molding-machines and tool
※ Mechanical machine construction
※ Steel and/or rolling mills
※ Machine building-and stone industry
※ Weir plants / ship building
※ Heavy duty machine industry
※ Welding engineering
※ Packaging industry
※ Lift and/or conveying engineering



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.

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
