Fabric Reinforced Composite (FRC)

Fabric Reinforced Composite (FRC) materials are used as high-performance bearing and guide ring elements inside hydraulic cylinders that operate in heavy duty environments, such as excavators being used in the construction and off-highway industries or face support cylinders used in the longwall mining industry.

The high compressive strength of fabric reinforced composite (FRC) materials makes them the ideal choice for bearings or guide rings in applications that suffer from severe misalignment or side load and where general engineering plastic bearing rings in materials such as Nylon cannot be used due to volume swell caused by water absorption.

FRC grades provided by DMR have an internal lubricant evenly dispersed throughout the material, providing a naturally low co-efficient of friction between the bearing, guide ring and the mating piston rod or cylinder bore of the hydraulic cylinder. As the surface of the bearing material starts to wear during operation it continues to disperse lubricant from within the structure, to ensure low friction operation at all times.

FRC materials offer the following benefits over general engineering plastics and filled PTFE bearing materials:

  • Superior compressive strength and load bearing ability
  • High wear resistance
  • Longer service life in heavy duty applications
  • Higher strength to weight ratio
