NYCAST® GX (Gray) is a solid lubricant filled nylon 6. NYCAST® GX was developed after years of research as an alternative to other “solid lubricated” cast nylons. GX gives engineers another superior choice from the NYCAST® family of premium grade cast nylons.

NYCAST®  GX is specially formulated, self-lubricating grades designed to:

  • deliver low coefficient of friction
  • superior wear resistance
  • high pressure/velocity performance
  • low moisture absorption

Typical applications include:

  • Wear pads
  • Bearings 
  • Thrust washers 
  • Bushings 
  • Gears

Applications in industries such as:

  • Construction
  • Mining
  • Pulp & paper processing
  • Food processing
  • Material handling
