Metal-Polymer Bearings

High Wear Resistance with Low Friction

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. 

GGB | Metal Polymer Materials

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 for Radial Loads

Cylindrical Bearings / Split Bushings 

Radial Loads

 

Flanged Bearings for radial loads and light axial loads

Flanged Bearings / Flanged Split Bushings

Radial Loads and Light Axial Loads 

 

Thrust Washers for heavy axial loads

Experience the Advantage

Low Friction Energy Efficiency
  • improved energy performance due to low friction property of PTFE-enriched overlay
Extended Service Life
  • from high wear-resistance bronze layer
  • from high overlay resistance under fatigue loading, cavitation erosion and edge loading 
Reduced/Zero Maintenance
  • from self-lubricating bearings that can operate dry without grease
  • from indents in the overlay which act as reservoirs for grease 
Increased Durability and Reliability
  • avoids potential shaft and bearing seizure under boundary lubricated conditions and frequent stop/start operation 
Compact, Lightweight Design
  • through thin-wall bearing construction
Reduced Noise
  • by eliminating metal-to-metal-contact between the bearing and the shaft
Efficient Operation  
  • improved operational efficiency with a machinable overlay for reduced clearances and perfect bearing geometry
