Graphite impregnated bronze bushings, also known as oil-free
bushings, are a highly efficient and long-lasting bearing solution.
These bushings are specifically designed to eliminate the need for
regular lubrication, significantly reducing maintenance
requirements and operational costs.
The key feature of graphite impregnated bronze bushings is the
integration of graphite particles within the bronze material.
Graphite is known for its excellent lubricating properties,
providing a smooth and friction-free surface even without the use
of external lubricants. This impregnation process ensures that the
lubricating properties of graphite are evenly distributed
throughout the bushing, providing consistent and reliable
performance.
The bronze material itself is renowned for its high strength,
durability, and corrosion resistance. Combined with the lubricating
properties of graphite, these bushings are able to withstand heavy
loads and extreme conditions while maintaining smooth and efficient
operation.
Oil-free bushings are ideal for a wide range of industrial
applications, particularly those that require reliable and
maintenance-free bearing solutions. They are commonly used in
machinery, pumps, motors, and other equipment where lubrication can
be challenging or impractical.
In addition to their lubrication-free operation, these bushings are
also easy to install and maintain. Their robust design and material
choice ensure long-term reliability and performance, minimizing
downtime and operational disruptions.
Overall, graphite impregnated bronze bushings provide a
cost-effective and efficient solution for oil-free bearing
applications, offering superior performance, durability, and
maintenance-free operation.

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 typical
VIIPLUS INTERNATIONAL has since established itself as a leading distributor of Bronze &
Steel Bushings , Sintered Bearings Products, Self-lubricated
