Long Life Lambda Chain

Long-Life Lambda Chain (X-Lambda)

The inclusion of an oil-impregnated felt seal in the construction of X-Lambda Chain helps provide far greater anti-wear performance than standard Lambda Chain.

If you wish fewer chain replacements than with regular Lambda Chain, then this is the perfect chain for you.

We reviewed the material and processing that go into our special oil-impregnated bushes, and improved the lubricant, giving it more than twice the wear life over previous products.

Basic Structure of Long Life Lambda Chain


Inner/outer link plates : coated black

Points of caution

The pins are longer than with Lambda Chain. Check your equipment for interference.


Lube-free, ultra long life
More than 5 times the wear life of Lambda Chain through the use of special oil-impregnated bushes and felt seals.

Performance under -10°C to 60°C Temperatures

Improved the lubricant used in the special oil impregnated bushes.
Used the compliant lubrication to NSF-H1 as special contained bush. It also can be used on food machinery. *
Compatible with Lambda Chain. However, the pins are longer than with Lambda Chain. Check your equipment for interference.
Operating temperature range:
-10°C to 60°C
RS Sprockets can be used. (Limited to single strand roller chain.)
