The SY 140DC/SY Roller Chain is a premium American Standard (ASA/ANSI) 1-3/4 inch pitch simplex chain featuring a double cap (double cover) design for enhanced pin retention and durability in demanding industrial applications. Engineered for reliable power transmission, this chain is suited to heavy machinery and conveyor systems operating under continuous load.
Manufactured to ASA/ANSI dimensional standards, the 140DC chain ensures precise engagement and compatibility with standard ANSI 140 sprockets and drive components. The double cap construction provides additional security at the pin ends, helping improve structural integrity and reduce the risk of component displacement in high-load or vibration-prone environments.
Constructed from high-strength, heat-treated steel with precision-formed rollers, bushings and reinforced pin assemblies, the 140DC/SY delivers dependable wear resistance, reduced elongation and consistent torque transmission. Supplied in a convenient 10 ft length, it allows flexible cutting and installation across a wide range of heavy-duty industrial systems.
