Antifriction Bearings

Tribology is the Science of Friction, Wear and Lubrication.

Find out how GGB's antifriction products and solutions offer improved bearing performance for your application.

GGB's antifriction plain bearings and bushings provide numerous benefits across a wide range of industries and applications, including aerospace, automotive, construction, energy, industrial, recreational and many more.

Over 60 years ago, GGB invented the original antifriction bearings and bushings DU® and DX® that disrupted the current technology of its time and quickly became the industry standard for high performance plain bearing solutions.

With the constant increase in customer demands and expectations for superior plain bearing performance, GGB's bearing range now includes over 50 distinctive antifriction bearing types including for example, DP4HI-EX®GAR-MAX®HSGEP® range, GGB-CSM® and GGB-CBM® products.

  • CAN GGB BEARINGS OPERATE DRY AND ELIMINATE THE NEED FOR LUBRICANTS?

    GGB’s range of self-lubricating bearing products are ideally suited to run under dry conditions, offering the final customer complete maintenance-free operation and the following advantages:

    • Reduced cost with simplified designs and assembly by eliminating lubricants.
    • Increased machine utilisation and efficiency with fewer stoppages for regular bearing lubrication.
    • More environmentally friendly operation by eliminating pollution risk from the lubricant. 
  • CAN YOU CONSIDER USING GGB SELF-LUBRICATING BEARINGS WITH A LUBRICANT?

    In oil lubricated systems, self-lubricating bearings are extremely beneficial especially when operating under boundary or marginally lubricated regimes.

    These regimes occur when the thickness of the lubricant film is too low to separate the two sliding surfaces in relative motion, thus risking contact and wear between the bearing and mating surface   A self-lubricated bearing, due to the nature of polymer overlay, will ensure friction, wear, heat generation and risk of seizure remains low during this contact period.
    This is particularly true for equipment running under periods of low-speed idling and frequent stop-start operation. Under such conditions, the self-lubricating properties of GGB bearings significantly improve machine efficiency, durability and reduce noise. 
     

  • HOW CAN GGB BEARINGS ACHIEVE SUCH HIGH LEVELS OF SELF-LUBRICATION AN EXCEPTIONAL MACHINE EFFICIENCY?

    The bearing surface layer is specifically formulated by GGB to work like a viscous grease that creates a transfer film to minimize contact of moving surfaces. 

    Furthermore, the majority of GGB bearings contain polytetrafluoroethylene (PTFE) in the sliding layer which provides exceptionally low coefficient of friction which minimizes energy consumption.

    The overall efficiency of equipment and machinery is therefore increased for reduced power input and a higher power output.

  • HOW CAN GGB BEARINGS EXTENDED SERVICE LIFE?

    The proprietary GGB bearing structure and overlay compositions include special anti-wear additives for high wear resistance to give extended service lives.

    Additionally, the inert nature of the Fiber Reinforced Composite and Engineered Plastics Bearings ranges ensures exceptional chemical resistance and are thus suited to many corrosive environments.

  • ARE PLAIN BEARINGS SIMPLE TO ASSEMBLE?

    Generally requiring inexpensive techniques and tooling, GGB bearings simplify assembly and can be mounted directly into the housing without the need of cooling or heating equipment.

  • WHAT ARE THE ADVANTAGES OF REPLACING ROLLER BEARINGS?

     

    Comparison roller bearings versus plain bearings

    Compared to roller bearings, plain bearings offer a greater contact area for a higher load capacity, an excellent resistance to shock loads and are more tolerant to edge loading.

    The compact one piece design of plain bearings allows a significant reduction in housing dimensions for substantial space and weight savings.

    Noise is reduced with the absence of internal moving parts and the plain bearing conformable liner offers superior damping properties.
