Description
16B-2 Duplex Roller Chain – ISO 606-B / DIN 8187
16B-2 is a two-strand (duplex) short-pitch precision roller chain with a 25.4 mm (1″) pitch and a minimum tensile strength of 106 kN. Duplex construction carries roughly twice the load of a single strand at the same pitch, so it suits higher-torque drives where increasing the pitch is not possible. Made to ISO 606-B / BS 228 / DIN 8187.
