The inner and outer plates are each blackened, giving them some corrosion resistance and a luxurious finish. To ensure compatibility with RS roller chain, the inner plate thickness is one size larger, and the tensile strength and Maximum allowable load are the same as those of RS roller chain. As a result, the pin length is longer than that of RS roller chain, so please check for interference with equipment when replacing.
- Size: RS40 to RS160
- Operating temperature: -10℃~150℃
Long-life Lambda Chain is a chain that significantly improves the wear resistance of Lambda Chain thanks to the effects of the oil-impregnated felt seal. It is ideal for those who wish to extend the replacement interval even further from Lambda Chain they are currently using. While it is compatible with Lambda Chain, the pin length is longer than that of Lambda Chain, so please check for interference with other equipment.
