Transmission Chain
We provide comprehensive types of transmission chains ranging from standard simplex/multiplex roller chains conforming to JIS, ANSI, and ISO standards to high fatigue resistance (LL series), lubrication free, stainless heat-resistant/corrosion-resistant type, and surface-treated chains, which are used in many industrial equipment such as automobile, industrial machinery, food industry, and logistics equipment.
Lubrication Free Chain
KCM lubrication free chain is a maintenance-free chain with self-lubricating capability using a special oil-impregnating bush.
Please use this product at a location where oil impregnation is not preferable or in-service oil impregnation is difficult.
KCM lubrication free chain have two types "NL" &"SL".
NL： Its rollers enable smooth mesh with sprockets.
SL：The chain is made of thick sintered sleeve, soaked in oil.
Nickel-plated version and a variety of attachments are also available.
Use this chain at the chain velocity of 150m/min or lower.
Should be used in the range of common operating temperatures (-10ﾟC to +150ﾟC).
Surface Treated Roller Chain
Surface treatment has been made on the standard steel chain to improve its aesthetics and add corrosion-resistance. Please select appropriate surface-treated chains for your applications requiring environment resistance.
Rustop (N): All parts are plated with special nickel.
DC coat (DC): The surface is treated with baked special film. Its color is mat silver white.
BC coat (BC): All parts have undergone a special mechanical surface treatment. Its color is mat dark gray. Meets RoHS directive.
DG coat (DG): All parts are treated with special coat and top coat. Meets RoHS directive.
Chain number： KCM 40, 50, 60, 80, 2040, 2050, 2060, 2080, 2080H
Silent Chain
The selection of a roller chain can be made in the following way:
Chain power transmission tables: transmission capacity values (kW) available based on the number of teeth of the small sprocket at the driving side and its number of revolutions (r/min).
Quick selection chart : a roller chain should be selected from a simple selection table based on the number of revolutions of the small sprocket (r/min) and the required transmission capacity (corrected kW).
General roller chain selection method: select a roller chain based on: 1. kW to be transmitted, 2.corrected kW, 3. rpm of driving shaft and driven shaft, 4. shaft diameter and sprocket boss
Low speed roller chain selection method: selection in a low-velocity transmission with its chain velocity of 50m/min or slower.
Documentation is available about the selection of roller chain length (number of links), center distance, temperature in the operation environment of the chain, its installation method, lubrication method, and appropriate lubrication oil after the selection of the chain.

High Fatigue Strength LL Series Roller Chain
KCM "LL (Long Life) Series Roller Chains have undergone intensive improvements in their fatigue strength from pursuing appropriate shapes for link plate to employing high strength steel for all of their parts. They have a higher fatigue strength and thicker plate.
Chain number： KCM 80LL, 100LL, 120LL, 140LL, 160LL
Chain number： KCM 60HLL, 80HLL, 100HLL, 120HLL, 140HLL
Strengthen Stainless Steel (AS) Roller Chain
To realize this product, the pins and rollers of SS chain have been replaced with those made of precipitation hardened stainless steel to improve its allowable load.
Its maximum allowable load is 1.5 times larger than SS chain. Please use this in case an SS chain will be short of allowable load.
Its corrosion-resistance is slightly lower than SS chain. Its operating temperature is -20ﾟC to +400ﾟC.
（Note: This product has magnetism since it contains precipitation hardened stainless steel.
Chain number： KCM 40 AS, 50 AS, 60 AS, 80 AS

Chain number： KCM 40 AS, 50 AS, 60 AS, 80 AS
Double-Pitch Roller Chain For Transmission
Double-pitch chain whose pitch is doubled compared to standard roller chain. Since it is using the same parts as standard roller chains except for link plate, the strength remains the same and the number of parts are reduced to the half of that of standard chains, which achieves weight and cost reductions. This roller chain is best suited for relative long power transmission at lowspeed.
Chain number： KCM A2040, A2050, A2060, A2080
Stainless Steel (SS) Roller Chain
This chain complies with JIS, ANSI, and ISO 606-B series standards and has employed SUS304 (18Cr-8Ni) austenite stainless steel for all its parts. It is appropriate to an environment that requires heat-resistance (-20 to 400ﾟC), corrosion-resistance, and aesthetics. With attachments installed, it can be used for transportation.
Note: KCM stainless steel roller chain has slight magnetism because it has been cold worked.
