Cast bronze bushings
Tin bronze alloys are typically found in gear, high-strength bushing and bearing applications where high strength and low speeds and heavy loads are present. Other high-strength applications for these alloys are pump impellers, piston rings, steam fittings and valve bodies. Tin bronze castings are utilized in movable bridge components, turntables for bridges and other structures for fixed and expansion bearings with slow or intermittent movement with heavy loads.
Manufacturer of continuous cast bronze bushings
It is a self-lubricating bearing material that consists of a high quality bearing bronze with solid lubricant pockets.
The self-lubricating graphite plugged bronze sleeve bushings are machined from continuous cast bronze bar stock. They are then milled and plugged with solid lubricant graphite based plugs. The plugged graphite bushings are great for applications where maintenance is difficult and where normal grease and oil based lubricants can burn off due to high temperatures. The cast bronze base material gives these products stronger bearing abilities when compared to other self lubricating bronze bushings.

1,In Chemical Composition, Single values represent maximums.
2,Mechanical performance of hardness value is only for reference.
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.
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.

Plug Graphite Sleeve Bushing
Inch Sized Bushings
Metric Sized Bushings
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
