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.

• NL: Its rollers enable smooth mesh with sprockets.
• 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).

Heat- and Corrosion-resistant Stainless Steel (SOS) Unlubricated Chain

Features of SOS Chain

1. Oil impregnation is not needed. Clean operating environment can be maintained without contaminating the unit through oil impregnation. (*1)(*2)
2. Since NSF-H1 registered lubrication oil (applicable to any location where accidental contacts with foods are expected) is used, the chain can be safely used for food processing machinery. Products with industrial lubrication oil impregnated are also available.
3. This chain is compatible with standard roller chains and accepts standard attachments.
4. Standard sprockets can be used for a multiple strand chain as well as a single strand chain.
   

The chain itself can be used in a low to high temperature range (-20ﾟC to 400ﾟC). (*3)
Note)
*1. Unless there are some problems in the use of stainless steel chain, lubricate it before using it.
*2. Do not use under complete oil-free condition.
*3. To bring out the best performance of its oil-impregnated bush, use this chain in the temperature range of -10ﾟC to 250ﾟC.
* The bush may wear out rapidly in a dusty environment. In addition, water splashing environment and higher temperatures make oil distill more easily from the oil-impregnated bush and reduce its life.

Heat and Corrosion-resistant Stainless Steel (SS) Double-pitch Chain

SUS304 (18Cr-8Ni) austenitic stainless steel is used for all the parts of this chain. It is appropriate to an environment that requires heat-resistance (-20 to 400ﾟC), corrosion-resistance, and aesthetics.
Note: KCM stainless double-pitch chain has slight magnetism because it has been cold worked.

Strengthened Stainless Steel (AS) Double-pitch 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.

Carrier roller chain (CY)

This is a new type of free flow chain replacing the top roller type. The position of its transportation rollers on its pitch line allows for more stable transportation than the top roller type.
Please select the roller material from plastic (DN), conductive engineering plastic (DNC), or steel (HS) according to the loading condition.

Triple speed Chain (CZ)

The special roller structure of this chain only requires approximately 1/2.5 velocity of chain compared to that of its pallet velocity. Therefore, this is the optimum choice for a line requiring quietness in running. In addition, since it has a excellent starting responsibility after accumulation compared to a common free flow chain, it is the best choice for an assembly line that repeats transportation and stagnation.
Select a roller material appropriate to the loading condition as for carrier chains.
There are several materials for roller available such as engineering plastic for low load (DP), conductive engineering plastic for low load (DPC), engineering plastic for middle load (DN), conductive engineering plastic for middle load (DNC), and steel for high load (HS).

Selection of Small Conveyor Chain

The selection of a small conveyor chain can be made in the following way:

1. Tentatively determine the type of chain considering the transmission method.
2. Check the allowable load of the rollers.
3. Check the maximum tension acting on the chain.
4. Check the transportation conditions.
5. Determine the chain size.

After selecting the chain, see the roller chain selection page for the documentation about the selection of lubrication methods and appropriate lubrication oils.
