Nyloil® (oil-impregnated cast nylon)


  • A cast nylon with built-in oil lubrication
  • Supe­rior machinability
  • Dura­bil­ity
  • Lubri­ca­tion results in 25% lower coef­fi­cient of fric­tion than other grades of nylon.
  • Per­forms in set­tings in which lubri­ca­tion is unde­sir­able, dif­fi­cult or impossible.
  • Oper­ates effi­ciently in direct con­tact with abra­sive slurries
  • Suc­cess­ful in marine applications
  • Reduced water absorp­tion pro­motes higher dimen­sional stability

  • Gears
  • Bear­ings
  • Bush­ings
  • Sprock­ets
  • Wear pads
  • Pul­leys
  • Guides
  • Insu­la­tors
