SENQCIA Inspire Series SBR British Standard riveted roller chain is manufactured in accordance with the ISO 606B International roller chain standard. These solid bushing/solid roller chains offer exceptional performance and long life in a wide variety of applications. Solid cold forged bushings extend chain wear life and greatly reduce break-in wear. 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 100ft reel.
