SY 40-2 AP Aqua-Proof ASA Duplex Roller Chain Connecting Link, 1/2 in Pitch

SY connecting links join the ends of a length of aqua-proof ASA duplex roller chain into a continuous loop. Each size here is matched to the SY chain of the same number, so select the link with the same chain number, strand count and series as your chain.

Made in Japan by Sugiyama Chain Co., Ltd. AIMS Industrial supplies these links individually. This listing covers 3 sizes (40 to 60). AP (Aqua-Proof) series chain pairs corrosion resistance with the strength of Sugiyama carbon steel roller chain.

Key specifications

Available sizes

Selecting the right option

For ASA (ANSI) chain the number is the pitch in eighths of an inch: 40 is 4/8 in (1/2 in), 60 is 6/8 in (3/4 in), 100 is 10/8 in (1-1/4 in). The figure after the dash is the number of strands.

Choose Aqua-Proof where carbon steel chain would rust but you still need carbon steel strength. For food contact, or anywhere coating flakes or wear dust could reach food, use stainless steel chain instead, as Sugiyama recommends.

Fitting and use

Fit the retaining clip or pin the way Sugiyama shows: spring clips go on with the closed end pointing the direction the chain runs, cotter pin prongs are opened to a 60 degree angle, and cotter pins must not be re-used. Use the clip or pin supplied with the link.

Do not use Aqua-Proof chain where it can contact food directly, or where coating flakes or wear dust could contaminate food. Use stainless steel chain for those jobs.

Chain drives should be guarded. Lock out machine power before removing, installing or servicing chain, wear eye protection when driving or grinding pins, avoid welding or plating assembled chain, and never repair damaged chain by replacing only some of its parts.
