The SY Super Roller Chain 1-1/2" Pitch Heavy ASA Simplex – Premium 10FT (120H-1SUPER/SY) is a high-performance American Standard roller chain engineered for demanding industrial power transmission. Designed in a Heavy (H) configuration with upgraded Super series components, this premium single-strand (simplex) chain delivers enhanced strength, wear resistance and extended service life in tough operating environments.
Manufactured to ANSI/ASA B29.1 standards, the 120H-1SUPER chain features a 1-1/2″ (38.10 mm) pitch and heavy-duty side plates for improved tensile strength compared to standard #120 chain.
