Strengths

The D&D Difference

Why D&D belts run stronger and last longer — and why distributors and OEMs standardize on them.

100% Vertical Integration

D&D controls belt manufacturing from start to finish — owning rubber tree plantations and belt molds, manufacturing their own cord and fabric, and mixing chemicals for proprietary compounds. No third-party sourcing or markups.

Independently Tested Best

In testing by the Akron Rubber Development Laboratory, D&D belts outperformed Gates and Browning in break-force strength by an average of 17%–34.7%, and stayed within 1.16%–3% in elongation.

Deep Inventory & Availability

Four U.S. distribution centers with 165,000 sq ft of storage, 35,000+ belt numbers, and 98% of orders shipping the same day.

Generation 3 Manufacturing

Elite belts are built with Gen 3 production that reduces human error and improves consistency, using aramid, fiberglass and steel-cord reinforcement for demanding drives.

Clean, Pure-Rubber Compounds

No recycled materials, clay, talc, or hazardous fillers — meaning low odor, superior durability, and none of the VOC issues of cheap filler belts.

Award-Winning

Named Power Transmission Belt Manufacturer of the Year by Manufacturing Outlook magazine.

Case Studies

Proven in the Field

Real results from distributors and end users who switched to D&D.

After 30 years in aggregate using just about every major brand, I was constantly re-tensioning because belts would elongate. Since switching to D&D, I typically re-tension once and they're good to go — a huge improvement, especially on larger 8V, C and D belts.
Scott StanderWest Side Tractor Sales Co.
No More Elongation
We chose D&D for selection, stock and customer service. Big or small, orders get the same great service — most go out same or next day, drop-shipped fast. D&D helps us keep production moving.
Howard RudinAce Belting Company
Big or Small, Same Great Service
D&D's support has been a major differentiator since day one. While backorders became common industry-wide during COVID, we rarely saw delays. Their belts hold up just as well, if not better, than many big-name brands.
Anthony SkracicGenesis Machine and Fabrication
A Partner Since 2017
I converted some customers' belts to D&D from Gates — pricing was better, and the quality far superior. Belts they had to replace per shift, per machine, lasted nearly two weeks on the first trial.
Valeri SamsFastenal Company
Superior Quality
Our customer assumed D&D belts would underperform versus the Continental brand they were used to. Once they started using them, performance matched their expectations — proving the quality was on par with what they'd run before.
Mark WirkusFastenal Company
Outstanding Performance
