The line is available in standard and double-sided configurations across a range of pitches, most commonly 8M, giving equipment builders and maintenance teams a chain-drive alternative that reduces lubrication and wear-related downtime.
Dura-Sync belts show up on conveyors, packaging machinery, and industrial drives wherever a maintenance team needs a dependable synchronous belt rather than a roller chain that requires regular lubrication.

Frequently asked questions
What is Dura-Sync?
Dura-Sync is an HTD timing belt product line manufactured by D&D PowerDrive, built as a reliable, economical alternative to chain drives for industrial power transmission. The belts use helically wound fiberglass tensile cords for strength and dimensional stability.
What is D&D PowerDrive's background?
D&D PowerDrive has more than 40 years of expertise manufacturing V-belts and timing belts, with its modern D&D Global organization established in 2006. The company now offers more than 35,000 belt configurations shipped from multiple U.S. locations.
What pitch sizes are Dura-Sync belts available in?
Dura-Sync belts are most commonly available in 8M pitch, though the line covers a range of timing belt pitches and both standard and double-sided tooth configurations. Double-sided versions are used on drives that need to transmit power or synchronize motion from both sides of the belt.
Why choose a Dura-Sync timing belt over a roller chain?
A Dura-Sync timing belt runs without lubrication and typically produces less noise and wear than a roller chain in equivalent industrial drive applications. That makes it a common retrofit choice for conveyors and machinery where chain maintenance has become a recurring downtime issue.
How do I find the right Dura-Sync belt through ChatMRO?
Search by the Dura-Sync part number printed on your existing belt, or describe the pitch, width, and length you need, and ChatMRO will match it to the correct replacement. Our RFQ form is available if you'd like our team to confirm the right belt for your drive.
