Types of Oil-Free Bushings

  • Solid polymer bushings are made from high-performance plastic materials, such as PTFE, which has excellent self-lubricating properties. These bushings are lightweight, corrosion-resistant, and can operate in a wide temperature range.
  • Sintered bronze bushings are made from porous bronze material, which is impregnated with lubricant during the manufacturing process. The lubricant is released slowly during operation, providing a low-friction surface for the mating parts.
  • Metal-Polymer Composite Bushings: made by combining a metal backing with a polymer-based self-lubricating layer.
  • Bi-Metal Bushings: consist of two layers: a steel backing and a self-lubricating layer made from materials like aluminum or bronze.

Why Use Oil-Free Bushings?

Graphite plugged bushings are beneficial anytime an application needs ongoing lubrication but also needs to perform for long periods without maintenance. These bearings are self-lubricating, so additional oil and grease are not needed.

Because graphite plugged bearings self-lubricate, money is saved on maintenance and replacement—both in materials and labor costs. Additionally, less downtime is needed to add more lubricant or perform other everyday maintenance tasks. Graphite plugged bushings have better wear resistance than other types of bearings. This is because when graphite plugged bushings are in use, there are very minimal friction thanks to the lubricant film they produce. Friction is what wears parts down and causes them to need eventual replacement, so limiting this is the key to durability.

Can Oil-Free Bushings Be Used In High-Load Applications?

Yes, oil-free bushings can be used in high-load applications, but it depends on the specific type of bushing and the nature of the load.

Oil-free bushings are designed to operate without the need for external lubrication, which can make them a cost-effective and low-maintenance option for certain applications. They are typically made from self-lubricating materials such as polymers or composites that have a low coefficient of friction and can withstand wear and tear.

However, the load capacity of oil-free bushings can vary depending on the material, design, and operating conditions. Some oil-free bushings may not be suitable for very high loads, especially if they are subjected to frequent or sudden impact or high-speed rotation.

It’s important to consult with our qualified engineer or bushing supplier to determine the best type of bushing for your specific application and load requirements. We can help you select a bushing material and design that can withstand the demands of your application while also providing reliable, low-maintenance performance.
