Lambda (Lube-Free)<strong>Roller</strong> <strong>Chain</strong>“Original” Lambda Lube-Free <strong>Roller</strong> <strong>Chain</strong>Drive <strong>Chain</strong>Lambda chain increases productivity and saves money.• Reduce maintenance time.• Eliminate product contamination.• Reduce downtime.Long life and low maintenanceLambda chains use special oil-impregnated bushings to provide lubrication and to prolong wear life.Ambient Temperature: –10°C - +60°C (+14°F - +140°F)0.5Wear Elongation (%)ANSI Standard RS<strong>Roller</strong> <strong>Chain</strong>Lambda0Operation Time• More than 14 times the wear elongation life of ANSI Standard RS <strong>Roller</strong> <strong>Chain</strong>(N.B. #120 and #140 have 5 times the life of ANSI Standard RS <strong>Roller</strong> <strong>Chain</strong>)• In-house testing comparison (non-lubrictaed operation).InterchangeableLambda <strong>Chain</strong> is interchangeable with ANSI Standard RS <strong>Roller</strong> <strong>Chain</strong>. However, as the pins are longer than that of StandardRS <strong>Roller</strong> <strong>Chain</strong>, please make sure that there is no interference with the machine.Operating Temperature–10°C - +150°C (+14°F - +302°F)SprocketANSI Standard RS <strong>Roller</strong> <strong>Chain</strong> sprockets can be used.
