FAQ

#80 vs ISO 16B?
Both 25.4mm pitch. Roller diameters are very close (#80: 15.87mm, 16B: 15.88mm) but internal widths differ. Verify all chain dimensions before pairing.
Coupling sprockets in #80?
Yes. #80 coupling sprockets with hardened teeth and black oxide coating for shaft-to-shaft chain coupling applications.
Max bore?
Up to 90mm+ with QD bushings on larger tooth counts. Plain bore up to ~75mm.
Segmental rim?
Yes. Bolt-on segmental rim #80 for large elevators and conveyors. Rim replacement without hub removal.
MOQ?
One piece with full material cert and inspection report.
