ANSI Lambda Chain
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 N.E.P. specification.

- 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, Lambda double strand chains require special sprockets.
- Due to increased roller link plate thickness, the pins are longer. Check for machine interference.
- Offset links for Lambda double strand chains are not available.
- When a single pitch offset link is used, please calculate a 35% reduction in fatigue strength.
