Self-Lubricating POM Bush: This low-maintenance polymer plain bearing features a marginally lubricated, three-layer composite structure, including cylindrical bushes and thrust washers.

POM layer of carefully sized, bearing quality bronze powder sintered onto the steel backing. This porous bronze inner layer is impregnated with the acetal resin and is securely sintered to the steel. The bronze also serves as an effective heat conductive path which minimizes undue temperature rise at the bearing surface and provides dimensional stability

Self-Lubricating POM Bushings: An Introduction and Their Advantages


Bushings, often referred to as plain bearings, are an integral part of many machines, providing a low friction interface between moving parts. As technology has evolved, so too have the materials used for these bushings. One of the most notable advancements in this field is the development of self-lubricating POM bushings. In this article, we’ll delve into what these bushings are, how they work, and the benefits they offer. sleeve bushings plain bearings POM composite 3 layer size copper brass bushes


What is a POM Bushing?

POM, or Polyoxymethylene, is a type of thermoplastic material known for its excellent mechanical properties. Also commonly referred to as Acetal or Delrin, POM has become a preferred choice for a variety of engineering applications due to its strength, stiffness, and dimensional stability.

A self-lubricating POM bushing is a type of bushing made from POM that has been imbued with lubricating agents. This design eliminates the need for periodic lubrication, reducing both maintenance time and cost.


How Does Self-Lubrication Work?

The concept behind self-lubricating POM bushings is straightforward. During the manufacturing process, lubricating agents are embedded within the POM material. As the bushing undergoes wear and friction, these lubricating agents are released onto the surface, ensuring a consistent layer of lubrication. This process greatly reduces the coefficient of friction and increases the lifespan of the bushing.


Advantages of Self-Lubricating POM Bushings

  1. Reduced Maintenance: One of the most significant benefits of self-lubricating bushings is the reduced need for maintenance. Traditional bushings require periodic lubrication to function optimally. With self-lubricating POM bushings, this need is virtually eliminated, recognized to reduced downtime and operational costs.
  2. Extended Lifespan: The continuous release of lubricating agents means that the bushing remains lubricated throughout its life. This reduces wear and tear and, consequently, increases the lifespan of the bushing.
  3. Environmentally Friendly: Since there’s no need for external lubricants, there’s a reduced risk of environmental contamination. This makes self-lubricating POM bushings a more environmentally friendly choice.
  4. Consistent Performance: The consistent release of lubricating agents ensures that the bushing’s performance remains optimal over time. This leads to more predictable and reliable machinery operation.
  5. Cost-Effective: While the initial cost of a self-lubricating POM bushing might be higher than traditional bushings, the reduced maintenance and longer lifespan often lead to cost savings in the long run.

Applications of Self-Lubricating POM Bushings

Self-lubricating POM bushings find applications in a variety of industries, including:

  • Automotive: Used in gear selectors, wiper systems, and door hinge mechanisms.
  • Industrial machinery: Employed in sliding and rotating applications where consistent performance is crucial.
  • Consumer goods: Found in household appliances and electronic devices.

Conclusion

Self-lubricating POM bushings represent a significant advancement in the world of machinery and equipment. With their reduced maintenance needs, extended lifespan, and consistent performance, they offer a compelling alternative to traditional bushings. Whether you’re designing a new piece of equipment or looking to upgrade an existing system, it’s worth considering the many benefits that self-lubricating POM bushings bring to the table.

Materials
They are produced from a material composed of the next three layers:

Designed for the marginal lubricating bushing. It is backed with copper-plated steel with porous bronze sintered on it and polymers (POM) embedded into the bores of the bronze. The steel back provides the products with high-quality low-carbon steel. Oil dents stamped on the surface of the polymer can achieve good lubrication between the bushing and its mating axis. It is of good anti-abrasion and load capability. The plating coating on the surface is erosion protective. And it is environmentally protective as no lead is included in the surface polymer POM. Products of the POM series are widely used on automotive chassis, forging machines, mine quarrying machines, metal smelting, and casting machines and in water irrigating and steel rolling industries.
