About ANSI #40-2 Stainless Steel Roller Chains
CTS® #40SS-2 Stainless Steel Roller Chain
The ANSI #40SS-2 is a 1/2-inch pitch duplex (two-strand) roller chain built from austenitic stainless steel. Two strands sit on shared pins with a 14.38 mm transverse pitch, so the chain carries roughly twice the load of a single-strand #40SS in the same envelope — 19.2 kN minimum tensile strength against 9.6 kN for the simplex version. Choose #40SS-2 when a single strand is not enough: higher transmitted torque, longer centre distances with less sag, or replacing two parallel single chains with one duplex drive.
