Embrace the Future of Friction Reduction: Metal-Polymer Anti-Friction Plain Bearings

In a world where machinery is integral to our lives, bearing solutions play a pivotal role in ensuring smooth operations. Whether it’s the motor vehicle you drive, the printing machine that produces your daily newspaper, or the sophisticated fitness machines at your local gym, bearings are an essential part of these systems. But not all bearings are created equal. It’s time to consider an alternative that’s not only more efficient but also kinder to our planet – the Metal-Polymer Anti-Friction Plain Bearings.

Metal-Polymer Plain Bearings are designed for use in a variety of mechanical movements, including linear, oscillating, and rotational actions. They excel in environments characterized by frequent starts and stops, where achieving minimal dry friction is essential, and where traditional lubrication methods are impractical. These bearings boast several key advantages, including high wear resistance, a low coefficient of friction, excellent corrosion and chemical resistance, making them ideal for situations where lubrication is difficult or impossible to apply. Additionally, the requirements for machining the parts that interact with these bearings are less stringent, allowing for their widespread application across various industries.

Technical Specifications & Composition: These bearings find extensive application in the automotive industry, including in steering systems, shock absorbers, door hinges, seat recliners, seat frames, and magnetic valves. They are also prevalent in general industrial applications, such as gear pumps, vane pumps, piston pumps, air cylinders, and hydraulic cylinders. Beyond these, they are used in material handling equipment, packaging machinery, textile machinery, forestry equipment, and household appliances, including air conditioners, fitness equipment, washing machines, and refrigerators.

• Layer 1 features a PTFE/Fibre mix with a thickness of 0.01 to 0.03mm, offering an outstanding initial transfer film that effectively coats the contact surfaces to initiate the self-lubricating property.
• Layer 2 is made of sintered bronze powder, measuring 0.20 to 0.35mm in thickness, providing a robust mechanical bond and superior thermal conductivity.
• Layer 3 consists of low-carbon steel, which lends mechanical strength and enhances thermal conductivity, underpinning the bearing’s overall performance.

Composition of Metal-Polymer Anti-Friction Plain Bearings

These self-lubricating bearings are designed with a metal-polymer composite material, comprising three integral layers:

1. Steel Back: This is the structural backbone of the bearing, ensuring robustness and mechanical strength.
2. Porous Bronze Sinter: Positioned atop the steel back, this layer acts as an interface between the steel and the top layer, retaining lubricant and releasing it as necessary to reduce friction during operation.
3. Polytetrafluoroethylene (PTFE) Surface Layer: This top layer of PTFE, known for its excellent anti-friction properties, further reduces friction and wear, eliminating the need for additional lubrication.

The result is an SF-1 bearing that offers low friction, anti-wear, and anti-corrosion properties, all without the need for any lubrication. It’s a cost-effective, low vibration, low noise solution that’s used in a wide range of machinery.

Applications of Metal-Polymer Anti-Friction Plain Bearings

With such a unique design, Metal-Polymer Anti-Friction Plain Bearings find their applications in various types of machinery:

• Printing Machines: Where precision and low noise are key.
• Textile Machines: For low friction and smooth operations.
• Tobacco Machines: Where robustness and low maintenance are required.
• Gym Equipment: To ensure silent and smooth user experience.
• Hydraulic Vehicles: To withstand heavy loads and rough conditions.
• Automobiles & Motorcycles: For reliable, smooth, and quiet operation.
• Agricultural & Forestry Machinery: For durability and low maintenance in harsh environments.

They are available in a range of standard dimensions and forms, such as cylindrical bushes, flanged bushes, thrust washers, flanged washers, and sliding plates, making them adaptable to a myriad of applications.

The Environmentally Friendly Choice

The absence of lead in these bearings makes them an environmentally-friendly choice. Additionally, the self-lubricating property eliminates the need for continuous lubrication, reducing both maintenance requirements and environmental pollution caused by waste grease.

By switching from traditional metal bearings to these innovative Metal-Polymer Anti-Friction Plain Bearings, you can not only extend the life of your machinery but also contribute positively to the environment. It’s time to invest in bearing solutions that offer superior performance and promote sustainability.
