Row spacing must match the chain<\/h2>\n<p>Multi-strand chains have defined transverse spacing between rows. The sprocket tooth rows must align with that spacing so each strand seats without side loading or forcing the chain plates against adjacent teeth. A useful field note for simplex, duplex, and triplex sprockets pairs duplex sprocket with multi-strand roller chain. That keeps the decision tied to the actual chain drive rather than a visual match.<\/p>\n<p>For procurement, express row spacing must match the chain as verifiable data: chain standard, measured dimension, drawing reference, material condition, or operating requirement.

Axial misalignment, runout, shaft deflection, or unequal tooth wear can cause one strand to carry more than its share.

The transverse tooth spacing must match the chain, so strand count is a dimensional compatibility requirement, not just a capacity label.<\/p>\n<\/details>\n<details style=\"background: var(--color-neutral); border-left: 4px solid var(--color-accent); border-radius: 8px; padding: 14px 16px; margin: 0 0 10px;\">\n<summary style=\"color: var(--color-brand); font-weight: bold; cursor: pointer;\">Can I use two simplex sprockets instead of one duplex sprocket?<\/summary>\n<p>Only if the design intentionally controls the exact row spacing, tooth phasing, axial retention, and alignment required by the chain. For normal replacements, a purpose-built duplex sprocket is the safer way to preserve the specified geometry.<\/p>\n<\/details>\n<details style=\"background: var(--color-neutral); border-left: 4px solid var(--color-accent); border-radius: 8px; padding: 14px 16px; margin: 0 0 10px;\">\n<summary style=\"color: var(--color-brand); font-weight: bold; cursor: pointer;\">How do I align a duplex roller chain sprocket?<\/summary>\n<p>First make the shafts parallel, then align corresponding tooth-row planes.
