SENQCIA Inspire Series™ 4-Pitch oil field offset Links are manufactured in Japan in accordance with the ASME/ANSI B29.1 American roller chain standard and possess an API certification (License Number 7F-0025). They offer exceptional performance and long life in primarily oil field drive applications.
Offset links are factory built 4 pitch sections with a roller link at each end. This assures the highest load carrying capacity it is possible to obtain for an offset link.
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. In the field it is necessary to install with two connecting links (sold separately). Care however should be taken as the offset link has less load carrying capacity than the base chain itself. Each offset link is individually packaged in a sealed plastic bag.
