Description
Multi-Strand Roller Chains – Duplex and Triplex (2, 3 and 4 Strands)
When a single-strand chain cannot carry the load within the space available, multi-strand construction adds capacity without increasing pitch. UIB supplies duplex, triplex and four-strand chains in both A-series (ANSI) and B-series (ISO 606 / DIN 8187) pitches, together with matched multi-groove sprockets.
