RS Roller Chain X-Λ Lambda Tsubaki RS Roller Chain X-Λ Lambda
The definitive lubrication free chain

Ultra long life
The inclusion of a felt seal in the construction of X-Λ has increased the anti-wear performance to more than 5 times that of Standard Lambda Chain. (In-company comparison) (-10°C~+60°C)

Cost reduction
Maintenance costs down + work ratio up = Overall cost reduction

Reduced maintenance
Reductions in lubrication, chain take-up, and machine positioning adjustments.

Increased productivity
Decrease in faulty product ration, reduction in chain replacement.

  • Operating temperature: -10ºC ~ +150ºC
  • Sprocket: Standard RS Roller Chain sprocket can be used as is. (Only for Single Strand Roller Chain)
  • Attention: Inner plate is thicker than Standard RS Roller Chain. Also, due to the insertion of the Felt Seal the pin is now longer (L1, L2). Please check for any interference.
