Material Selection Guide

Self-lubricating bearings are a category of bearings that are designed to provide their own lubrication during operation. This is achieved through materials that either contain lubricants within their structure or have the ability to transfer lubricating materials to the contact surfaces during use. The selection of the appropriate self-lubricating bearing material is crucial for ensuring optimal performance, longevity, and reliability of the bearing in various applications.

Please submit the technical drawings for custom self-lubricating bearings manufacturing. Take the necessary time to ensure that every detail is clear and that the drawing aligns with accepted standards. Additionally, ensure that your drawing undergoes all quality assurance and approval procedures. A drawing that is easy to follow and clearly defines your requirements is essential for the successful manufacturing of the part.

Proper alignment and tolerances are critical for the performance of self-lubricating bearings. Designers must ensure that the housings and running surfaces are adequately aligned and that the stiffness matches the loading assumptions

The initial transfer film created by a lead-free polymer fiber mix coats the mating surface of the bearing assembly, establishing an oxide-type solid lubricant film. Sintered bronze powder enhances thermal conductivity away from the bearing surface and acts as a repository for the PTFE mix. A steel backing underpins a high load-carrying capacity, affording the wrapped bearings superior heat dissipation.

Copper/tin plating offers robust corrosion resistance. These versatile and highly durable wrapped bearings are suitable for a myriad of applications. We welcome discussions on how PTFE lined wrapped bearings can be integrated into your projects.

WRAPPED ACETAL LINED BEARINGS STRUCTURE: Wapped acetal lined bearings exhibit high wear resistance and low friction, even with minimal lubrication. Their surface is patterned with circular indents which should be filled with grease during assembly. The low carbon steel base provides a high load-carrying capacity and outstanding heat dissipation.

Beyond Our Conventional Steel-Backed, Ptfe Lined Wrapped Bearings, We Also Present Our Bronze Backed And Stainless Steel Series Featuring A Bronze Or Stainless Steel Backing Strip. These Are Ideal For Applications Where Standard Steel Does Not Suffice. The Range, Dimensions, And Tolerances Of These Bearings Align Precisely With Those Of Our Standard Ptfe Lined Wrapped Bearings.

Our selection of wrapped acetal lined bearings is designed for applications involving rotary and oscillating movements. These bearings are notable for their extended re-lubrication intervals, lack of water absorption, superior damping qualities, and minimal susceptibility to edge loading. The pom composite bearing bushing range is an excellent choice for the automotive, machinery manufacturing, and agricultural sectors, as well as any setting where continuous lubrication is unfeasible. Here are a few examples where our composite bearing bushing range is utilized:

• Rear chassis hinges
• Articulation joints
• Drill spindles
• Gearboxes and clutches
• Grinding and milling machines
