BS Lambda Chain

BS Lambda Chain

Lambda Chain that conforms to ISO 606 B series standards.

The dimensions are fully interchangeable with existing BS chains.

Improved the lubricant in our special oil-impregnated bushes to give the chain 30% longer wear life over our previous products.


Improved wear life
Achieves a longer wear life thanks to Tsubaki's original bearing material, material properties, and oil. By thoroughly minimizing quality deviations, Tsubaki BS Series Lambda Chain demonstrates reliable performance.
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. *
Easy cutting
Uses a "Center sink pin", which requires no pin grinding during chain cutting, reducing chain cutting and connecting times. Center sink pin

Used from RS08B to 16B-LM-1
