Cast Bronze Bushings China CuZn25Al5 

What is Cast Bronze Bushings? Cast Bronze Bushings is made of Cast Bronze Bushings with Solid Lubricant Inserts, the base metal withstands high load and the graphite provide self-lubrication.

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
