Gasket cast bronze graphite plugged bronze bushings, also known as oilless bearings, are a type of self-lubricating bearing system that utilizes the unique properties of graphite and bronze to provide superior wear resistance and durability.
These bushings are cast from bronze alloy, often C86300, which is a high-tin bronze alloy that offers excellent corrosion resistance and mechanical strength. The graphite plugs or inserts within the bushings provide a continuous lubricating film between the moving surfaces, eliminating the need for external lubrication.
The gasket design of these bushings allows for easy installation and replacement, while also providing a seal against contaminants and moisture. This ensures that the bearings remain in optimal condition, even in harsh environments.
Graphite plugged bronze bushings are commonly used in a wide range of applications, including robotics, heavy machinery, and industrial equipment. They are ideal for applications where lubrication is difficult or undesirable, as well as for applications that require long-term reliability and durability.
In summary, gasket cast bronze graphite plugged bronze bushings, or oilless bearings, offer a self-lubricating bearing solution that provides superior wear resistance, durability, and ease of installation and maintenance.
Our VIIPLUS plain bearings are available in metric and imperial sizes from stock. Our in-house machining service is able to produce non-standard sizes to suit specific customer requirements.
