Hankuk Chain Lubrication-Free Roller Chain

Hankuk Chain Lubrication-Free Roller Chain

Lubrication-free roller chain with oil-impregnated sintered bushings that provides long chain life without lubrication.

Key features

  • Sintered bushings, no lubrication required
  • Special surface treatment of plates and plated pins for corrosion and abrasion resistance
  • About 14 times the life of standard chain (RNL120/140: about 5 times)
  • Pin longer than standard chain - check interference before use
  • Applicable temperature -10 to 60 C
  • Plated version available
