SY 50-3 ASA Triplex Roller Chain Offset Link (Half Link), 5/8 in Pitch
Available
SY offset links (half links) let a length of ASA triplex roller chain be made up with an odd number of pitches. Each size here matches 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. Supplied individually. This listing covers 8 sizes (40 to 160). Where possible, choose a chain length with an even number of pitches so that no offset link is needed.

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.
SBR is the standard choice for most drives and conveyors. Step up to H, HE or SUP H where loads are heavy or shocked, or to Aqua-Proof, stainless steel or self-lube chain where the environment calls for it.
Fitting and use
An offset link is handy where the chain needs an odd number of pitches, but Sugiyama notes it is at least 35% lower in fatigue strength than the chain itself and recommends against it where frequent impact loads at high speed are involved. A two-pitch offset link is available for that duty.
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.
