Tsubaki's Lambda Chains were the first in the industry to use a special oil-impregnated bush. Since their launch in 1988, they have been adopted for diverse industries and applications, and their performance has been highly rated. Tsubaki has a wide line-up of lube-free, long life products that help customers reduce costs.
ANSI Lambda Neptune™ Chain is a Tsubaki ANSI Lambda chain that has undergone a special surface treatment. The link plates have a special two stage layer applied in order to provide the maximum protection from the operating or environmental conditions. (Spring clips are SUS301). Both ANSI Lambda Neptune™ rollers and pins have undergone a special coating designed to resist the corrosive conditions as well as the severe dynamic contact between roller and sprocket. This chain is suitable for use in applications that are subject to alkaline cleaning and environments exposed to seawater, acid-rain and other adverse weather conditions. This chain does not contain any chemically hazardous substances such as Hexavalent Chromium, Lead, Cadmium and Mercury as regulated by RoHS√. The kilowatt ratings are the same as those of the corresponding BS chain with a working temperature range: -10°C to +150°C. Above +60°C a special high-temperature lubrication is required.
