High Wear Resistance with Low Friction

Metal-Polymer Bearings

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 PTFE or high performing thermoplastic combined with fillers to obtain an optimal running surface.

Offering superior anti-friction and wear-resistant properties, Metal-Polymer bearings can operate dry or with external lubrication—delivering superior performance through its unique composite structure. 

To keep innovating in the space of tribological bearings, we continue to push ourselves to increase wear resistance while improving friction. Recent advances that deliver improved tribological properties are creating opportunities to meet these challenges and help revolutionize component design and manufacturing. Ideal for hundreds of applications in a variety of global industries, Metal-Polymer solutions are easily customized for customer specifications and requirements: from grooves and holes for lubricant to punched and stamped shapes. 

The Freedom to Innovate

In any project, considering tribological requirements as early as possible in the system design process is critical to ensuring optimal performance or expand beyond traditional surface engineering solutions. This allows you to take full advantage of part shape to minimize the number of components and maximize service life. Depending on your application’s requirements, our Metal-Polymer bearings can be customized for a wide range of uses. Many shapes and sizes are possible—with inner diameters ranging from 2mm/0.08in to more than 500mm/20in. 

 

Finally, the type of loading applied to a bearing determines which shape is required from the following:

  • Cylindrical Bearings / Split Bushings 
    • Radial Loads
  • Flanged Bearings / Flanged Split Bushings
    • Radial Loads and Light Axial Loads 
  • Thrust Washers 
    • Heavy Axial Loads 
  • Flanged Thrust Washers 
    • Heavy Axial Loads 
  • Sliding Plates 
    • According to Final Shape

Experience the GGB Advantage
