Note: 1. Drive and Conveyor series LAMBDA chains cannot be intercoupled or interchanged. 2. The heavy roller link plates slightly increase the width, which means Drive LAMBDA connecting links are required. 3. Connecting links for RSD80NP-LAMBDA to RSD140NP-LAMBDA and RSD80(H)NP-2LAMBDA to RSD140(H)NP-2LAMBDA have cottered pins. 4. Double Strand Drive LAMBDA requires heavy-series sprockets.
* R indicates riveted, C indicates cottered. ** Width between roller link plates (W) is slightly narrower than ANSI standard, however this chain runs on standard sprockets.
LAMBDA for international standards • Operates in temperatures up to 302°F • Replaces BS/DIN chain • Cost effective, lube-free operation

Note: 1. Although some dimensions differ from British Standard (BS/DIN), the primary dimensions are identical, enabling BS-compatible LAMBDA to engage perfectly with British Standard sprockets. 2. The heavy roller link plates slightly increase the width, which means drive LAMBDA connecting links are required.
