BS Lambda Attachment Chain KF Series


- Introducing the new KF Series Lambda Chain, which is compatible with the ISO606 B series.
- This Lambda Chain complies with BS standards and can be used in the food industry and in high temperature areas.
- *Please consult us regarding chain selection.
Features
-
・Can be used in high temperature ranges
Can be used in high temperature ranges from -10℃ to 230℃. Stable lubrication and wear resistance.
-
- Reduction of maintenance man-hours
special oil-impregnated bush are used, eliminating the need for oiling the chain, and maintaining a clean working environment without the need for additional oiling to contaminate the equipment.
-
·sprocket
Please use sprockets for BS roller chains (ISO standard B series). (Made to order)
Compatible sizes: RS type attachment chain RS08B-LM to RS16B-LM
Improved lubricant for special oil-impregnated bush, suitable for use in food machinery
- special oil-impregnated bush are lubricated with NSF H1 compliant lubricant, so they can also be used in food processing machinery.
- Please be aware that NSF H1 non-compliant rust prevention oil and assembly oil are also attached in the process of manufacturing.
Lambda Chain Basic Structure

*This structural diagram is for RS Attachment Chains.
・What is NSF H1?
NSF is an organization that certifies the safety of lubricants for food processing machinery.
NSF H1 is a standard established by NSF that states, "Lubricants can be used in areas where accidental contact with food may occur."
Precautions
- -This product is made to order.
- - We can also manufacture special attachment shapes and special extension pins, as well as BS/DIN double pitch chain and RF06B, RS20B, and RS24B chains with attachments.
Please contact us. - ・When replacing a European-made chain with a standard Lambda Chain, please be aware that the dimensions may differ from our standard dimensions, so please check the attachment dimensions beforehand.
- - At temperatures above 230°C, the wear life will be significantly reduced. Also, do not use at temperatures above 280°C, as there is a risk of toxic gases being generated.
When selecting sprocket specifications
It is necessary to select a sprocket specification that corresponds to the customer's operating environment and chain specifications.
Use standard steel BS sprockets with BS Lambda attachment chains.
When using hardened tooth tips in high temperature ranges (above 150°C), the surface hardness of the teeth may decrease. Please contact us for details.

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.
