DP11: New Metal-Polymer Material Offers Low Friction, Improved Dry Wear Resistance

April 26, 2010


GGB DP11 Low-friction metal-polymer composite plain bearing

GGB Bearing Technology, formerly Glacier Garlock Bearings, has developed a PTFE-based, metal-polymer bearing material for industrial applications requiring low friction and excellent dry wear resistance.

The new metal-polymer composite material of DP11 provides improved dry wear performance under high-frequency and low-amplitude oscillating movements, even at high operating temperatures in a diverse range of applications:


  • Cutting equipment

  • Textile machinery
  • Clutches
  • Dampers
  • Belt tensioners
  • Dual mass fly-wheels
  • + many more

Eliminating Lubrication in Extreme Operating Conditions

The material structure consists of a steel backing, a porous bronze interlayer and a sliding layer of PTFE with solid lubricant and fillers, allowing the bearings to withstand maximum static loads of 250 MPa and maximum dynamic loads of 140 MPa. GGB’s DP11 bearings are capable of sliding speeds up to 2.5 m/s dry and are suitable for use under operating temperatures ranging from -200°C to +280°C.

Manufactured to low tolerances for reduced operating clearances, the dry-running bearings eliminate the need for lubrication and maintenance, reducing equipment and operating costs and improving performance.

Environmentally Friendly Bearings, Tailor-Made Solutions

The DP11™ material is available in a variety of configurations manufactured to users’ specific requirements, including:

  • Cylindrical and flanged bearings
  • Strip
  • Modified standard components
  • Thrust washers
  • Flanged washers
  • Half bearings
  • Flat components
  • Deep-drawn parts
  • Pressings and stampings

DP11 is manufactured under the DIN EN ISO 9001, ISO/TS 16949 and ISO 14001 approved quality management systems and complies with both the European Union’s End of Life Vehicles (ELV) directive and Certain Hazardous Substances in Electrical and Electronic Equipment (RoHS) regulation.
