SENQCIA Ultra-Max® Heavy Series offset Links are manufactured in Taiwan in accordance with the ASME/ANSI B29.1 American roller chain standard. The link plates of the heavy series are one size thicker than standard roller chains providing additional strength in heavy duty applications.
Offset links are supplied with “flatted” connecting pins and a split cotter for ease of assembly in the field. These special purpose links allow the user to make an endless strand of roller chain from an odd number of pitches. They are also used to reduce the length of a strand by one pitch when normal chain elongation has created excess catenary sag on a roller chain drive. Care however should be taken as the offset link has significantly less load carrying capacity than the base chain itself. Each offset link is individually packaged in a sealed plastic bag.
