The "Acetal Metal-Polymer Self-Lubricating Sleeve Bushing with Thin Wall Burnishing" is a high-performance bearing component that combines the durability and strength of metal with the self-lubricating properties of acetal polymer. This innovative design features a thin wall sleeve bushing, which undergoes a burnishing process to enhance its surface finish and overall performance.
Acetal, also known as polyoxymethylene (POM), is a thermoplastic polymer renowned for its excellent wear resistance, low friction coefficient, and good mechanical properties. When combined with metal reinforcement, the resulting hybrid material offers a unique combination of strength, stiffness, and self-lubrication, making it ideal for applications requiring high load capacity and long-term reliability.
The thin wall design of the sleeve bushing minimizes the overall weight and size of the component, allowing for more compact and efficient designs in various industrial applications. The burnishing process, a finishing technique that involves pressing a rotating tool against the surface of the bushing, smoothes and hardens the surface, reducing friction, wear, and noise. This enhances the bushing's ability to withstand repeated motion and pressure while maintaining tight tolerances and precise fitments.
The self-lubricating properties of the acetal polymer within the bushing ensure smooth operation even in environments where traditional lubrication may be difficult or impractical. This eliminates the need for frequent maintenance and reduces downtime, making the Acetal Metal-Polymer Self-Lubricating Sleeve Bushing with Thin Wall Burnishing an attractive solution for demanding applications such as automotive, aerospace, machinery, and heavy equipment.
In summary, this innovative bushing design leverages the advantages of both metal and acetal polymer to provide a lightweight, durable, and self-lubricating bearing solution that can withstand harsh conditions and improve overall system performance.
A unique, composite sleeve bearing material POM, made to order from china, is a composite strip plate material made up of three layers: steel, porous bronze, and acetal resin polymer:1. Steel backing 2. Porous bronze innerstructure.
Mineral mountain machinery, hydraulic industry and rolling steel industry, etc. It is without lead, can meet the requirements of environment protection. Our POM type bushings & washers are especially well-suited for applications where lubricant can not be supplied continuously or repeatedly. Recommended for applications involving intermittent operation or boundary lubrication.

The lubricant film that the bearing surface is able to maintain during long periods of sliding contact with a shaft or flat surface ensures negligible wear. Should the bearing
be allowed to run after the film of lubricant has disappeared, some wear will occur; but there will be no damage to the mating surface until the bronze substrate surface is exposed.
