RF Double Pitch Chain Λ Lambda (C-Λ)
The latest in lube free chain-Tsubaki "Lambda Series" drive chain
Superior wear life without lubrication-more than 14 times longer than standard roller chain (#35, #120, #140, five times longer) 1.5 to 10 times longer than brands of oil sealed chain. 1.2 to 20 times longer than lube free chain.
