The dimensions are fully interchangeable with existing BS chains.

We reviewed the material and processing that go into our special oil-impregnated bushes, and improved the lubricant.

Reduces time and cost of import purchasing replacement chain from equipment maker due to many European-made machines being used, and contributes to longer service life.

We could also request attachment shapes specific to our machines.

The chains used in wrapping machines especially are imported from Europe, and thus the shape of the attachments is unique.

Chains and sprockets at Tsubaki are semi-standardized, allowing for smooth procurement.

The customer approached us about product quality problems from chain oil and wear elongation they were having on their European printing machines. Because the product is paper, there can be no oil stains whatsoever. So they used Lambda Chain, which also helped them increase their conveyor's operating efficiency.

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.
