4 Improved the oil-impregnated sintered bush material and processing methods.* Improved the oil used in the sintered bushes. *New BS/DIN Lambda chains were launched in June ICE Now with the wear life. Basic Lambda Chain construction Lubricant (Uses NSF-1 food grade lubricant) Sintered bush NS-1 standards he NSF is the only global organization that certifies the safety of lubricants for food equipment. NSF-1 standards stipulate that the lubricant can be used in areas where lubricant may come into accidental contact with food. Lube-free, long life, and eco-friendly Oil-impregnated sintered bushes are made in-house for stabilized quality and higher performance. e began manufacturing our oil-impregnated sintered bushes in-house from Further, by streamlining production management we were able to stabilize quality and increase chain performance. Far less maintenance time and costs he chain doesn t need to be lubricated thanks to its special oil-impregnated bushes no more dirty equipment from additional lubrication to help you maintain a clean working environment. Much higher productivity Benefits of Lambda Chain Less maintenance time elps maintain a clean work environment igher equipment reliability Much lower chain replacement costs 3

5 his is our biggest improvement to Lambda Chain since we first launched it in ith the huge undertaking to move sintered bush production in-house in 2014, we decided to review the sintered bush material and improve part precision to further increase quality. e also introduced totally new production methods, equipment, and inspection equipment to stabilize quality even further to allow us to mass produce the bushes and achieve better wear performance. e threw out conventional ways of thinking regarding lubricant for the sintered bushes and tested and evaluated lubricants that were developed under completely new standards. his allowed us to develop a lubricant that not only conformed to NSF-1 standards, but also provided even better wear performance. I have complete confidence in all the improvements we made in everything from design to manufacturing for subaki s new Lambda Chain. I hope that both current and future users will enjoy the long life benefits that the new Lambda Chain will bring them. 4

6 subaki Lambda Chain subaki is a pioneer in the industry, being the first to develop a roller chain that uses special oil impregnated bushes. Since first being introduced in 1988, Lambda Chain has gained an outstanding reputation in a variety of industries and applications. It is capable of meeting a wide range of customer needs for long life in a lubrication-free environment, resulting in reduced overall long-term costs. Lambda Chain uses NSF-1 lubricant, so it is safe to use on food equipment. Special oil-impregnated bushes provide long Long life without additional lubrication service life. Food grade lubricant Sintered bushes use NSF-1 conforming lubricant* Compatible with standard RS Compatibility Chain. (*k ratings will differ.) Operating temperature range Sprocket -10 C to 150 C Can use Standard RS sprockets (single strand roller chain only) Basic Construction erformance in Ambient emperatures (-10 C to 60 C) Special nickel plated pin Special oil-impregnated bush Lambda Chain (standard) Inner and outer link plates use a special black oxide coating Lambda chain (nickel plated) Uses a special nickel plating (except on the bushes) 0.5 ear Elongation (%) 0 Overseas competitor lube free chain Japanese. competitor lube free chain Running ime New Lambda Chain revious Lambda Chain In-house tests, lube-free operation Lambda is a registered trademark of U.S. subaki oldings, Inc. in the United States. BS Lambda Chain (ISO 606 B Series) Lambda Chain that conforms to ISO 606 B Series. he dimensions are fully interchangeable with existing BS chains. Specially shaped pins are used on single-strand 08B to 16B to enable easy chain disassembly using a standard chain breaker. Safety recautions for Lambda Chain 1. Do not use Lambda Chain if the chain will come in direct contact with food or where coating flakes or wear dust can contaminate food. Also, in non-food applications, appropriately cover the chain or contact a subaki representative about chain selection if using in environments where coating flakes or wear dust present problems. Although nickel is not subject to the Japan Food Sanitation Law or the Industrial Safety and ealth Law, plating on sliding parts can peel. 2. Do not use Lambda Chain where there is the possibility of exposure to chemicals, water, or wash down/degreasing operations. 3. Oil may spatter depending on the operating conditions. *Be aware that non-nsf-1 grade anti-rust agent or assembly oil from the manufacturing process may be present on Lambda Chain. 5

7 Long Life Lambda Chain (X-Lambda Chain) (atented) he inclusion of oil-impregnated felt seals between link plates significantly improves the wear resistance of standard Lambda Chain. Ideal for environments where even longer replacement intervals compared to standard Lambda Chain are required. Ultra long life without additional lubrication Food grade lubricant Compatibility Operating temperature range he combination of a special oil-impregnated bush and felt seal further extends service life. Sintered bushes use NSF-1 conforming lubricant.* Compatible with standard Lambda Chains. owever, as the overall pin length is longer than with Lambda Chain, check that there will be no interference with the machinery or other equipment. -10 C to 60 C.

8 Applications Dusty Environments he customer uses chain on their raw steel material conveyor. owever, when they lubricated in the dusty environment the lubricant would turn sludgy and the chain would suffer poor articulation. So, they used standard chain without lubrication, but the chain suffered from a short service life. hey improved the wear life of their chain by switching to lube-free Lambda Chain. Automotive arts he customer uses Double itch Lambda Chain with outboard rollers on their automotive parts accumulating conveyor because it reduces the time they need for maintenance. Chocolate Lambda Chain is used in the chocolate cooling process. Oil from the chocolate can mix with chain lubricant and stick to it, so additional lubrication needs to be avoided. hat s why the customer uses Lambda Chain on their chocolate manufacturing lines. 7

9 Construction Material Dryer Outer walls are loaded onto a bar conveyor and passed through a furnace to dry. he customer previously used standard chain but the high temperatures led to premature wear. KF Series Lambda Chain greatly extended the life of their chain. Spaghetti Spaghetti is hung from a bar and dried on a conveyor. he customer uses Lambda Chain to avoid any lubrication contaminating the product. Food Dryer Bars are attached to extended pins so that the chain can be used as a net conveyor in a food dryer. he customer used standard chain with no additional lubrication to avoid contaminating the food, but the chain would wear prematurely. hey switched to Lambda Chain for a much longer wear life. 8

Chain is coated with less rust-prevention oil than those for RS Chain, which may lead to premature rusting. Bush oil can leak out in a vacuum, decreasing wear resistance. Do not use in a vacuum. Contact a subaki representative when considering a chain that can be used in a vacuum. Chain life will decrease dramatically if oil in the oil-impregnated bushes is depleted. Kilowatt ratings for double-strand Lambda Chain (multi-strand coefficient): he multi-strand coefficient of a double-strand chain with the same part dimensions of a single-strand chain is 1.4. o achieve the same multi-strand coefficient of 1.7 as double-strand RS Chain, the outer and inner plates must be thickened and a heavy-duty FCL (press fit) must be used.

49 Selection (Lube-Free Drive Chain) 1. Lube-Free Drive Chain Selection Select lube-free drive chain using selection methods based on k ratings tables Kilowatt Ratings (See page 16 for tables) Kilowatt ratings are dependent on the following factors: 1) Indoor environment with a temperature range of -10C to 60C and where no wear dust is present. 2) No corrosive gases, high humidity or other harmful elements are present. 3) he two sprocket transmission shafts are maintained parallel to each other and the chains are properly installed. 4) No possibility of exposure to chemicals, water, or cleaning/degreasing. 5) No significant load change during conveyance Operating Factors As the drive capacity of the chain is subject to various application factors, the following table has been designed to rectify kilowatt changes in relation to load fluctuation. able 1: Operating Factors ype of Impact Smooth ransmission Small-impact ransmission Large-impact ransmission ype of Machine ower Source Belt conveyors with small load fluctuations, chain conveyors, centrifugal pumps, centrifugal blowers, general textile machinery, general machines with small load fluctuations Centrifugal compressors, marine engines, conveyors with some load fluctuations, automatic furnaces, dryers, pulverizers, general machine tools, compressors, general construction machinery, general papermaking machines resses, crushers, construction and mining machines, vibration machines, oil-drilling rigs, rubber mixers, rolls, roll gangs, general machines with reverse or large impact loads Step 1: Selection Factors Motor or urbine Internal Combustion ydraulic Non- Drive ydraulic 1) ype of machine 2) ype of impact 3) ower source 4) Kilowatt rating 5) Diameter and rpm of high-speed shaft (small sprocket) 6) Diameter and rpm of low-speed shaft (large sprocket) 7) Distance between shafts Step 4: Determine Chain and Small procket eeth Number Using the Kilowatt Rating ables and referring to the rpm of the small sprocket, determine the appropriate chain and the number of teeth of the small sprocket that satisfy the corrected kilowatt value. For smoother chain drive, the smallest pitch chain with the required k is recommended. For double-strand LMD and LMD- chain, multiply the multi-strand coefficient 1.4 for LMD and 1.7 for LMD- by the k ratings in the Kilowatt Rating ables to determine the appropriate chain and the number of teeth of the small sprocket that satisfy the corrected kilowatt value and small-sprocket rpm. Step 5: Determine Large Sprocket eeth Number he number of teeth for the large sprocket is determined by multiplying the number of teeth of the small sprocket by the speed ratio. A small sprocket with more than 15 teeth is recommended. owever, the number of teeth on the large sprocket should be less than 120. By reducing the number of teeth on the small sprocket, the number of teeth on the large sprocket can be reduced. Even in this case though, the number of teeth on the small sprocket should not be reduced to less than 13. Step 6: Confirm Shaft Diameter After determining the number of teeth necessary for the small sprocket, refer to the RS Sprocket Dimension able (separate catalog) to check if the sprocket diameter satisfies space limitations KF Series Lambda Drive Chain Selection Corrected k < k ratings = Catalog k ratings x temperature coefficient *KF Series is usable if the k ratings are greater than the corrected k. Select KF Series by multiplying the temperature coefficient of the operating environment found in able 2 by the k ratings.

In some cases, it may be difficult to determine the most appropriate chain size and type, since there are a variety of operating conditions for the conveyor. he general procedure for chain selection is as follows: Step 1: Check conveyance conditions Step 2: entatively determine chain type Step 3: Check allowable load of rollers and attachments Step 4: Calculate maximum chain load Step 5: Determine chain size In this catalog, values are indicated in both SI and gravimetric units. he weight (kf) used to calculate the max. load in the gravimetric units is the same value as the mass (k).

Configuring chain to a specific length will require disassembling units Firmly lock the chain in a chain vise. Using a grinder, grind down the ends of the two pins on the outer link (on the same side) until they are level with the link plate. ake care that the grinder does not overheat. Use a dedicated cradle and an RS Chain punch to disassemble the chain. Using a primary punch suitable for the chain size, place the punch on the head of the pin that was ground down and strike with a hammer. Be sure to strike the pins on the outer link alternately to remove them evenly and at the same time. Strike the pins until they are just about to release from the outer plate.
