BS Roller Chain Lambda Features

This advanced 4thgeneration BS Roller Chain Lambda, offering a wider line-up and easy cutting capabilities, was redesigned to make it more simple and convenient to use.

5 New Points

  1. Wider Range
    7 sizes are now available with the addition of RF06B, RS20B and 24B to the existing lineup of RS08B, 10B, 12B, and 16B. Standardization of single and double strand chains has also greatly increased the range of available types from 4 to 14.

  2. Easy Disassembly
    Through the adoption of newly developed special shaped pins and a new riveting style, chain can be disassembled with the aid of a chain breaker only (for single strand RS08B to 16B).

  3. Easy Replacement
    In further pursuit of BS roller chain "replacement ease," we have now made it possible to use single and double strand chains on ISO standard sprockets. Standard attachments have also been added.

  4. Easy Adoption
    Drive and conveyor chains have now been unified with emphasis being placed on the "easy adoption" of all attachment types and extended pins. The pin diameter of extended pin attachments also conforms to ISO standards.

  5. Easy Identification
    New stamping on outer plates enables end-users to recognize TSUBAKI LAMBDA more readily.

3 Basic Points

  1. Long Life
    Long-term operation without additional lubrication is made possible thanks to the combined effect of the special oil-impregnated bushings and specially coated pins. Compared to standard BS roller chain, wear life has been greatly improved and waste generation has been reduced.

  2. High Strength
    High fatigue strength is assured by the Ring-Coined(RC) connecting links and shot-peened parts.(NB: Not applicable for link plates with attachments)

  3. Corrosion Resistance
    Each inner and outer link plate has been individually blackened. As well as increasing corrosion resistance of the link plates, the blackening also improves the overall appearance of the chain.

Interchangeability

  • Make sure to replace the whole chain when replacing old specification chain.
  • Old specification chain and connecting parts cannot be used together with the new specification chain.
