  • Ideal for replacing RS roller chain Double Strand
  • - This chain has the same transverse pitch as a double-strand RS roller chain, making it possible to use double-row RS sprockets.
    (Standard Lambda double-strand sprockets are required.)

Features

  • 1. General-purpose RS sprockets can be used

    RS Double Strand Compatible Lambda Chain has the same transverse pitch as RS roller chain. Standard double-strand sprockets can be used, which is also cost-effective.

    What is multiple strand factor?

    A coefficient for calculating the power transmission capacity of a double-strand chain. It can be calculated by multiplying the value in kW ratings table by the multiple coefficient.

When selecting sprocket specifications

It is necessary to select a sprocket specification that corresponds to the customer's operating environment and chain specifications.

For RS Double Strand Compatible Lambda Chain please use standard steel RS sprockets.

Standard sprockets can also be used with multiple strand chains.

Please see the chain and sprocket compatibility chart here.

Points to note when considering and adopting Lambda Chain

  • 1. Foreign matter contamination prevention: Do not use the chain in cases where it comes into direct contact with food or where there is a risk that peeling debris or wear debris may get into the food.
    Even when using in environments other than food where peeling debris or wear debris is a problem, please take measures to prevent foreign matter from entering, such as by installing an appropriate cover.
    Nickel plating is not subject to regulation under the Food Sanitation Act or the Industrial Safety and Health Act, but please be careful if you are concerned about the plating peeling.
  • 2. Regarding product oil: Depending on the conditions of use, the oil impregnated in the bushings may splash out.
    Due to manufacturing reasons, Lambda Chain has a small amount of oil on it that is not NSF H1 compliant.
    If the oil impregnated in the bushing is lost, it will rapidly run out of oil, leading to wear elongation and the end of its life.
  • 3. If dust or other debris is present in the operating environment, the product may wear out and reach the end of its service life earlier than expected.
    Do not use the bushing in an environment containing chemicals, solvents, or degreasing agents that may remove the oil impregnated in the bushing, or in water or under vacuum.
    Lambda Chain is not coated with anti-rust oil, so please store it away from high temperatures, humidity, and dust.
  • 4. Regarding double-strand chains: transverse pitch of Lambda Chain and Heavy-duty Lambda Chain (including coated and KF Series) differs from that of RS roller chain.
    Please use the dedicated sprocket instead of the RS sprocket.
    RS Double Strand Compatible Lambda Chain has the same transverse pitch as RS roller chain. RS double-strand sprockets can be used.
    LMD-2 and LMDS-2 chains cannot be used together, including connecting parts such as connecting links. When replacing the chain, please select a compatible sprocket.
  • 5. Check for interference with the equipment. The pin lengths for Lube-free chains vary depending on the thickness of the outer and inner plates and whether or not a felt seal is used.
    The pins are longer than those of RS roller chain, so please check for interference with equipment when replacing.

Comparison of wear life in high temperature ranges (reference)

The wear life of a roller chain varies depending on the chain speed, load acting on it, number of sprocket teeth, condition, environment, temperature, and other conditions.
The diagram is for reference only.

*The wear life of Lambda Chain is determined to be over when it reaches +0.5% of the total length of the chain.

  • Note: 1. The operating temperature range for Lambda Chain is -10°C to 150°C.
  • 2. The chain temperature may exceed the ambient temperature. Be careful not to let the chain temperature exceed the operating temperature.
  • 3. At temperatures between 150°C and 200°C, the transmission capacity will drop to 3/4 of the catalog value. Please select a product that is appropriate for the temperature.
  • 4. At temperatures below 200°C to 230°C, the transmission capacity will drop to half of the catalog value. Please select a product that is appropriate for the temperature.
