Flange Graphite Impregnated Brass Bearings are mechanical components that offer superior wear resistance and self-lubricating properties. These bearings are manufactured from brass, a copper-zinc alloy, which is then impregnated with graphite particles to enhance its lubricating capabilities.
The flange design of these bearings allows for easy installation and secure fitment within the application. The graphite impregnation process involves infiltrating the brass matrix with graphite particles, creating a composite material with enhanced lubricity. This eliminates the need for external lubrication, reducing maintenance requirements and downtime.
Graphite impregnated brass bearings are commonly used in applications that require smooth and reliable rotation or sliding motion. They are suitable for applications involving rotating shafts, pivot points, and other moving parts where low-friction and wear-resistant properties are crucial.
The brass material offers excellent corrosion resistance and durability, while the graphite impregnation ensures smooth operation and reduced wear. These bearings are often used in industries such as machinery, automotive, aerospace, and marine, where they perform reliably in harsh environments and demanding conditions.
When selecting Flange Graphite Impregnated Brass Bearings, it is important to consider the specific requirements of your application, including the dimensions, load capacity, and operating conditions. It is also recommended to consult with a manufacturer or supplier to ensure that the bearings you select meet your needs and will perform optimally within your system.

Graphite impregnated bronze slide plate is a self-lubricating bearing plate made up of a high quality bronze with graphite filled grooves.
The bronze plate acts as the bearing surface, withstanding heavy loads, while the graphite inserts provide a solid, oil-free lubricant. The formation of lubricant forms a film of graphite between the bearing and mating surface which results in low co-efficient of friction upon the start of relative motion.

Graphite plugs provide self-lubrication. Graphite has some unusual properties that make it an excellent lubricant. Chemically, it is one of three common allotropic forms of carbon (amorphous carbon and diamond being the other two). In contrast to diamond, which has a very dense and strong three-dimensional crystal structure, graphite has a two-dimensional crystal structure - strong in two dimensions but weak in the third. Its atoms are arranged in parallel sheets that are easily sheared off, giving graphite its characteristic slippery feeling. For example, if you were to rub a pencil lead between your fingertips, it would feel oily. That feeling is the sliding and peeling off of crystal sheets.
In the self-lubrication process, it is precisely these sheared off crystal sheets that provide the lubrication, somewhat like a piece of tissue paper between two pieces of glass. Initially there is no lubrication but as the two mating surfaces (e.g., bushing and shaft) move in relation to each other, a minute amount of graphite becomes distributed over the wear surface and acts as a solid lubricant. It will stay there a long time due to graphite’s superior stability. Although graphite sublimes at 10,000 F in a reducing atmosphere, it will oxidize in air at about 500 F, so it is important to maintain temperatures well below this threshold. In addition, graphite has a near-zero coefficient of thermal expansion. When a graphite plug is embedded into a metal part, the metal will expand but the graphite plug won't. The plug loosens, which restricts the temperature range to about 200 F if the plugs have any open surfaces (i.e., not constrained by a mating part).
