Lambda BS Attachment Chains KF Series
- Introducing Tsubaki's new KF Series BS Lambda Chain, which conforms ISO606 standards.
- BS Lambda Chain that can be used in the food industry and in high temperature environments.
- ※Please inquire for chain selection.
Features
-
・Can be used in high temperature range
Can be used in the high temperature range of -10 ℃ to 230 ℃. Lubrication performance and wear performance are stable.
-
・Reduction of maintenance man-hours
Uses a special oil-impregnated bush. Since there is no need to relubricate the chain, the equipment is not contaminated by additional oil and a clean working environment is maintained.
-
・Sprocket
Use a sprocket for BS roller chain (ISO standard B series). (Made-to-order )
Compatible size :RS Chain with attachment RS08B-LM~RS16B-LM
Improved lubricating oil for special oil-impregnated bushes, can be used in food machinery
- Since NSF H1 compliant lubricants are used for the lubricating oil of special oil-impregnated bushes, they can also be used for food machinery.
- Please be aware that NSF H1 non-compliant rust prevention oil and assembly oil are also attached in the process of manufacturing.
Basic Structure of Lambda Chain
※The structural diagram shows an RS Attachment Chain.
・What is NSF H1?
NSF is the organization that verifies the hygienic quality of food lubrication.
NSF H1 is the standard regulated by NSF. This is "Lubricant ingredients are safe in the event of incidental food contact." oil.
Notes
- ・Made to order
- ・Special attachment shapes, special extended pins, and BS/DIN Double Pitch chains and RF06B, RS20B, RS24B chains with attachments are also available.
Contact a Tsubaki representative. - ・When replacing a chain with a standard attachment made in Europe with a Lambda Chain, the dimensions of the attachment may differ from our standard dimensions. Check the dimensions of the attachment in advance.
- ・Do not use in environments over 230℃. This will lead to a serious decrease in wear life. Also, do not use at temperatures above 280 °, as there is a risk of toxic gas being generated.
When selecting sprocket specifications
It is necessary to select a sprocket specification that corresponds to the customer's operating environment and the chain specification used.
Please use standard BS steel sprockets for Lambda BS attachment chain.
When using hardened teeth sprocket in a high temperature range (150°C or higher), the surface hardness of the tooth may decrease. Please consult us for details.

Point of cautions when considering and adopting Lambda chains
- 1. Preventing contamination
Lambda Chains have special nickel-plated pins and plates with black oxide treatment. Surface-treated Lambda Chains have different surface treatments for each series. Do not use Lambda Chain if the chain will come in direct contact with food, or where coating flakes or wear dust may contaminate food.
In non-food applications, take measures to prevent entry of foreign matter, for example, installing an appropriate cover when used in environments where coating flakes or wear dust may present a problem.
Though nickel is not subject to the Japan Food Sanitation Act or the Industrial Safety and Health Act, use the chain with caution. - 2. Lubricating oil used on products
Depending on usage conditions, the lubricating oil contained in impregnated bushings may spatter.
Due to manufacturing constraints, Lambda Chain uses certain oils that are not compliant with NSF H1 requirements.
If a bushing runs out of impregnating oil, it should be quickly re-oiled, leading to a longer wear life. - 3. Operating environment
If debris or dust is allowed to enter between chain parts, wear elongation may result and the chain may reach the end of its service life prematurely.
Avoid using chains in a chemical, solvent, or degreasing medium, or in water or under vacuum in a way that may cause the lubricating oil impregnating the bushings to become depleted.
Lambda Chain is not coated with anti-rust oil. Keep away from hot or humid places, and avoid dusty locations. - 4. Double-strand chain
Double-strand Lambda Chain and Heavy Duty Lambda Chain (including Surface-treated Series and KF Series) have different transverse pitches compared to RS Roller Chain.
Use dedicated sprockets instead of RS sprockets.
RS Double-strand Compatible Lambda Chain has the same transverse pitch as RS Roller Chain. Double-strand RS sprockets may be used.
Double-strand chains cannot be used together with LMD-2 and LMDS-2 chains, including their connecting components such as connecting links. The entire chain should be replaced and compatible sprockets selected. - 5. Checking for interference on the equipment side
The length of pins for lube-free chains varies depending on the thickness of the outer and inner plates and the presence or absence of a felt seal.
Since the pins extend beyond the RS roller chain itself, check for interference with equipment at the time of chain replacement.
