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).

- Pin is longer than that of standard chain because inner plate is thickened. Avoid interference with equipment.
- In case of single strand chain, standard sprocket can be used. In case of multiple strand chain, exclusive sprocket is required.
- Maximum allowable load is determined based on tensile breakage, not on strength of bushing.
- Connecting link of 80NL is of split pin type.
