SENQCIA Inspire Series™ SBR® cottered roller chain is manufactured in Japan in accordance with the ASME/ANSI B29.1 American roller chain standard and possess an API certification (License Number 7F-0025). These solid bushing/solid roller chains offer exceptional performance and long life in primarily oil field drive applications.
Solid cold forged bushings and a patented pin treatment extend chain wear life and greatly reduce break-in wear. Middle link plates are press fitted for maximum fatigue strength. All side plates are broached to improve pitch-hole quality and maximize load carrying capacity. Cottered chains are specified for oil field chains to allow field assembly or disassembly as required.
Packaged chains are pre-lubricated with high quality wax-type grease and come with a necessary connecting link to join the ends. Offset links (used to shorten or lengthen a chain strand by 1 pitch) are also available and sold separately. This chain is packaged in a 10ft box.
