SENQCIA Inspire Series Hollow pin type ANSI/ASME offset links are manufactured . They offer excellent resistance against many forms of chemical attack and operate in temperatures ranging from -250 to +750 degrees F. Hollow Pin chains are primarily used on a conveyor with through rods inserted into the hollow pins 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.
