Graphite bush bearings, specifically the C86300 grade, are widely used in various industrial applications due to their unique properties and oil-free design. These bearings offer several advantages such as excellent self-lubricating properties, high temperature resistance, and corrosion resistance, making them suitable for demanding environments.
The C86300 grade of graphite bush bearings is composed of a copper-based alloy with a high percentage of graphite particles embedded within the matrix. This combination provides the bearings with excellent wear resistance and the ability to operate without the need for external lubrication.
The oil-free design of these bearings significantly reduces the risk of contamination and the need for maintenance, making them ideal for applications where lubrication may be difficult or undesirable. Additionally, the self-lubricating properties of the graphite particles allow the bearings to operate smoothly and efficiently over extended periods of time.
Graphite bush bearings are available in a variety of sizes and configurations to meet the specific needs of different applications. Wholesale suppliers offer these bearings at competitive prices, allowing customers to purchase in bulk and save on costs.
In summary, graphite bush bearings made from C86300 grade material are a reliable and cost-effective solution for applications requiring oil-free, self-lubricating bearings. Their unique properties and durability make them a popular choice among industrial users.

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. With Graphite Plugged Bronze Bushings no form of supplementary lubrication is required.
The surface layer is improved with graphite to achieve the lowest coefficient

The wear resistance metal back with the solid lubricants can continuously provide lubricating source during the bearing operation to achieve the self-lubricating feature. With the combination of heavy load and impact resistance of the metal and low friction factor of the non-metal, this material is good for the various working conditions.
