Oilless bushings, also known as sleeve bearings, are a type of self-lubricating sliding bearing.

Oilless bushings are used to support sliding motions by reducing friction and increasing stability. Because of their self-lubricating properties and versatility in terms of usage, oilless bushings are a very popular component in industrial applications. Oilless bushings are cylindrical and can be made in any girth and length.

Self Lubricating Oilless Bushing Design

The fact that oilless bushings require no maintenance makes them very convenient, and their self-lubricating properties make them long-lasting and highly efficient.

Oilless Bearing : Sintered bronze bushing and casting bronze bushing with solid lubricant

Sintered Bronze bushing is frequently made of bronze powder, which is fused to create a porous surface in which impregnated oil can be stored. As the bearing is used, the oil continually recycles itself onto the surface of the oilless bushing, making them self-lubricated.

Oilless Bushing Bearing With Solid Lubricant

When not made of a metal like bronze powder, oilless bushings are made of casting bronze with solid lubricant. These materials commonly include tin bronze, Aluminum bronze, and others. choose our graphite oilless bushing bearing means lower costs, less maintenance, and no need to apply grease as they are fully self-lubricating.

Graphite Oilless Bearing Material

Graphite Plugged Bushings are a complete line of Self-Lubricating Bushings that excel whenever standard lubrication is impractical, including heavy load, and high-temperature applications. They are manufactured from a variety of Bronze Alloys, including C95400 Aluminum Bronze, C93200 Bearing Bronze, and C86300 Manganese Bronze.

• Self Lubricated when standard lubrication is impractical
• Performs well under various loads, types, and speed operations
• Resists corrosive and hostile environments
• Excellent performance in medium to high temperatures up to 600° F
• Compatible with most viscous lubricants & Oil and Grease applications

The applications for graphite-plugged bushings are virtually unlimited. From hard-to-maintenance applications to high-temperature environments to heavy-loaded applications, graphite-plugged bronze bushings exhibit excellent service and wear resistance.
