The Bestorq AX Series are raw-edge, notched (cogged) belts engineered for efficient power transmission and cooler operation—especially on smaller pulley diameters. The precision cog profile improves flexibility and reduces bending losses, while the construction meets ARPM standards for reliable, low-maintenance service life.
Easy Replacement & Compatibility
Bestorq AX belts interchange with classical cogged A-section belts from Gates®, Goodyear®, Carlisle®, and other major brands. Match your existing belt number (e.g., AX15) to the Bestorq equivalent for a drop-in replacement.
Specifications: AX (A-section, cogged) belts have a nominal top width of 1/2 in (0.50 in) and a height of 5/16 in (0.3125 in). Lengths available on this page typically range from ~17.2 in to ~138.2 in (AX15–AX136).

I ordered two of these and one of them was brand new but the other was used.
Thank you for your feedback, Andrew. We strive to provide our customers with the highest quality products, and we sincerely apologize for the mix-up with your order.
