SY 40-1 SLR-TS Self-Lube ASA Simplex Roller Chain Connecting Link, 1/2 in Pitch

SY connecting links join the ends of a length of self-lube ASA simplex 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 4 sizes (40 to 80). SLR series chain carries its own lubricant in sintered, oil-impregnated bushings and is lubricated before delivery.

Where this product is used

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 SLR where relubricating is impractical. Sugiyama lists this ANSI size as SLR-TS, the self-lube chain for drives, which has the same strength as standard carbon steel chain and a longer pin length than SBR, so check clearances. Keep it away from water, chemicals and shock loads.

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.

Service life drops sharply if the lubricant in the bushings is depleted, and the lubricant seeps out quickly above about 70 °C operating temperature.

Wet or dusty environments can lead to premature wear. Sugiyama does not recommend SLR chain where it is exposed to chemicals, water or shock load.

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.
