Tsubaki's Lambda Chains were the first in the industry to use a special oil-impregnated bush. Since their launch in 1988, they have been adopted for diverse industries and applications, and their performance has been highly rated. Tsubaki has a wide line-up of lube-free, long life products that help customers reduce costs.

  • Connecting links are clip type for sizes RS40-LMD to RS60-LMD, and cotter type for sizes RS80-LMD to RS140-LMD.
  • Drive and Conveyor series Lambda chain cannot be intercoupled or interchanged.
  • Due to increased roller link plate thickness, Drive Lambda connecting links are required.
  • Due to increased roller link plate thickness, the pins are longer. Check for machine interference.
  • When a single pitch offset link is used, please calculate a 35% reduction in fatigue strength.
  • The listed sizes are stock items, other chain sizes are available on request
  • Also available in Neptune™ specification.
