-
Cost-Effective: By reducing the need for external lubrication and maintenance, self-lubricating bearings offer cost savings over their operational life.
Types of Self-Lubricating Bearings
There are various types of self-lubricating bearings designed to suit specific application requirements. Some common types include:
-
Metal-Backed Bearings: These bearings feature a metal substrate with a layer of special solid lubricating material. They offer low friction coefficients, high load-bearing capacity, and resistance to impact and high temperatures.
-
Composite Bearings: Composite bearings combine a metal substrate with a self-lubricating composite material, such as PTFE or graphite. They excel in reducing friction and wear while providing excellent self-lubricating properties.
-
Plastic-Based Bearings: Plastic-based self-lubricating bearings utilize high-performance polymers with embedded solid lubricants to offer low friction and self-lubricating capabilities.
Do Oil-Free Bearings Need Oil?
Oil-free bearings, also known as self-lubricating bearings, are specifically designed to operate without external lubrication. They possess a composite layer of solid lubricants that continuously provides the necessary lubrication for smooth and frictionless motion. These bearings work efficiently even with minimal or no oil application.
Versatility of Oil-Free Bearings
Oil-free bearings find applications in diverse environments, including chemical, wet, dry, and pollution-prone conditions. Their ability to operate without external lubrication makes them ideal for industries where traditional lubricants may not be feasible or practical.
Selecting the Right Bearings

Composite lubricated bearings, also known as oilless bushings, are innovative bearings that offer maintenance-free and self-lubricating properties. These bearings consist of a metal backing, typically made of steel or copper, with a sintered porous copper interlayer. The interlayer is impregnated with PTFE (Polytetrafluoroethylene) and additives, along with a solid lubricant placed in holes or grooves on the friction surface. This unique combination ensures continuous lubrication during operation, resulting in reduced friction and wear.
The working principle of composite lubricated bearings involves the transfer or counter-transfer of the solid lubricant to the friction surface. As the bearing operates, a strong and adherent solid transfer film forms on the friction surface. This film provides excellent lubrication, uniform coverage, and enhanced protection against friction and wear.
The advantages of composite lubricated bearings are numerous:
-
Maintenance-Free Operation: These bearings eliminate the need for external lubrication, making them maintenance-free and reducing the need for frequent inspections and reapplications of lubricants.
