Graphite Plugged Oilless Bush 500SP Bearings are self-lubricating bearings that are designed to operate without the need for external lubrication. These bearings are filled or "plugged" with graphite, which provides excellent lubrication properties, reducing friction and wear during operation.

The 500SP designation likely refers to a specific size, series, or standard of the bearing, though it's not a universally recognized designation. It's important to consult with the manufacturer or supplier to ensure you are selecting the correct bearing for your application.

Graphite Plugged Oilless Bushings are commonly used in applications where lubrication may be difficult or impractical, such as in high-temperature or high-speed environments. The graphite filler acts as a lubricant, enabling the bearing to operate smoothly and efficiently without the need for regular lubrication.

These bearings are suitable for a wide range of applications, including machinery, automotive, aerospace, and other industrial applications. They can be used in rotating or sliding motion and are often paired with shafts, pins, or other rotating components.

The graphite-filled material provides superior wear resistance and durability, making Graphite Plugged Oilless Bush 500SP Bearings a reliable choice for demanding applications.

Graphite is mechanically forced into the holes/grooves under extreme pressure. These bearings offer continuous lubrication over long periods without maintenance.

Since self-lubricating bearings are maintenance-free and wear resistant under dust and outdoor conditions, they are widely used in oil cylinders, suspension systems, joints and other parts that cannot be refueling or are difficult to form oil film.

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.
