Wet environments can cause the oil in the oil-impregnated bush to leak. Bushes are also coated with lessrust-preventing oil, causing early rusting.Bush oil can leak in a vacuum, decreasing wear resistance. Do not use in a vacuum.The life of the chain will decrease dramatically if oil in oil-impregnated bush is depleted. (See "(9) Lambda Chain Life" on pg. 168.)KW ratings for double-strand Lambda Chain (Double-strand coefficient)The coefficient of a double-strand chain with the same part dimensions of a single-strand chain is 1.4. To achieve the same coefficient ofmulti-strand RS Roller Chain, the outer and inner plates must be thickened, and an H class FCL (press fit) must be used. In any event,sprockets must be customized - double-strand RS-type sprockets cannot be used.Double-strand Lambda Chain pin lengthBecause the inner plate is thicker than that of an RS Roller Chain, the pin is longer by an equal amount (L1 and L").
