Marginal Lubricating Metal Polymer Plain Bearings are a specialized type of bearing designed to provide optimal performance in lubrication-constrained environments. These bearings feature a polymer material, primarily polytetrafluoroethylene (), which is renowned for its excellent lubricating properties and low friction coefficient.

The combination of metal and polymer in these bearings creates a robust yet lubricating surface that can withstand high loads and temperatures while maintaining smooth operation. The marginal lubricating design ensures that even in conditions where lubrication is limited, the bearings can still function effectively, reducing wear and extending bearing life.

's inherent chemical resistance and non-stick properties also contribute to the bearings' durability and performance, making them suitable for a wide range of applications in industries such as machinery, automotive, and chemical processing. Marginal Lubricating Metal Polymer Plain Bearings are an excellent choice for those seeking high-performance bearings that can handle challenging lubrication conditions.

Metal-Polymer Marginal-Lubricating Bearings

Viiplus Metal-polymer marginal-lubricating bearings maintenance-free steel backing series

A Metal-polymer marginal-lubricating bearings is comprised of a metal shell and a very thin polymer coating () applied to the inside.

Choose from our selection of Metal-polymer marginal-lubricating bearings in a wide range of styles and sizes. In stock and ready to ship.

Consisting of a metal backing for high mechanical strength and a sintered bronze layer, Metal-Polymer bearings are impregnated with an anti-friction overlay enriched with or high performing thermoplastic combined with fillers to obtain an optimal running surface.

Features Of Metal-Polymer Composite Bearings

It is suitable for boundary lubricating applications. It is recommended to lubricate the components with grease before assembling. The oil deposit can hold the lubricant with optimized matrix and to hold possible incoming containments during the operation. Lubricating during the operation helps to prolong the bearing duration. The wideoperation temperature range of -150°C-+250°C and the reliable chemical resistance of the bearing ensure suitable applications under middle to high load conditions. CSB-80M is a material with PEEK/ thickness of 0.1-0.2mm without oil deposits on the surface, it is a machinable material after assembling.

1. Strength and Stiffness and Low Friction

When a steel backing is combined with or POM, the strength and stiffness properties are enhanced by the low friction of the polymer material. The use of a polymer layer such as also deals with issues such as corrosion and unwanted chemical interactions by providing protection the metallic layer(s).

2. Many composite bearings are, by their very nature, dry-running.

They can be designed so that no grease or lubricant is required, which can be very important for applicants that are sensitive to contamination or other instances where grease could pose a problem. When designed correctly composite bearings can provide extreme low friction, almost eliminate issues with stick-slip, and reduced break-away torque requirements.

3. Dimenstional Stability

Another issue that composite bearings can address quite well is dimensional stability.Some polymers are especially susceptible to dimensional changes through absorption of water or reactions to temperature variations. The use of composites can significantly reduce those problems.

Structure:

1. PEEK/ thickness 0.20~0.35 mm, provides good wear resistance. This bearing surface carries a pattern of circular indents which should be filled with grease on assembly of the bearing.

2. Sintered bronze thickness 0.20-0.35mm, provides strong mechanical bond and excellent thermal conductivity.

3. Low-carbon steel, provides mechanical strength and thermal conductivity.

Composite Options for Bushings and Bearings

When it comes time to select a bushing or bearing for a particularly sensitive application, it might be wise to add composites to your list of potential bearing materials. Composite bearings may be primarily metal with a low-friction polymer lining, or they may be filament wound fiber reinforced materials with a polymer matrix. Regardless of which type of composite bearing is under consideration, remember that they can offer added benefits such as improved strength, stiffness, wear properties, and reduced friction while possibly eliminating the need for lubricants.

Typical Applications

The material has wide operation temperature range and can be used under high PV value condition. It is used in hydraulic motors, pumps, diesel engine common rail system and heavy truck brake systems.
