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.

Long-Life Lambda Chain (X-Lambda)

1. 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.

2. Features

Lube-free, ultra long life
Use of special oil-impregnated bushes and felt seals give this chain longer life.
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:
-10ºC to 60ºC
RS Sprockets can be used. (Limited to single strand roller chain.)

Safety Precautions for Lambda Chain

  • Do not use Lambda Chain if the chain will come in direct contact with food or where coating flakes or wear dust can contaminate food. Also, in non-food applications, appropriately cover the chain or contact a Tsubaki representative about chain selection if using in environments where coating flakes or wear dust present problems. Though nickel is not subject to the japan Food Sanitation Law or the Industry Safety and Health Law, plating on sliding parts can peel.
  • Do not use Lambda Chain where there is the possibility of exposure to chemicals, water, or cleaning/degreasing vapors.
  • Oil might spatter depending on the usage conditions.
  • Please be aware that NSF H1 non-compliant rust prevention oil and assembly oil may be present on the chain.
