32mm wide · 19mm deep · Raw-edge cogged · Multiple leading brands
DX belts are the cogged version of D section, with notches moulded into the underside so they bend more easily, run cooler and grip better on the heaviest drives. They’re used on crushers, mills and quarry plant, large compressors and pumps, big industrial fans, sawmills and heavy agricultural machinery, and are a straight upgrade on a smooth D belt. We stock DX belts from leading manufacturers. Search by the code on the old belt, such as DX180, and use the filters to narrow it down by length or brand.

Finding the right DX belt
Reading the codeDX180 means a DX cogged belt with a 180 inch inside length (4572mm). Metric sizes may show the inside length (Li) or the datum length (Ld), which is 75mm longer, so check which your belt uses.
Upgrading from D?A DX belt runs in the same pulleys as a smooth D belt of the same length, so a DX180 can usually replace a D180 directly. Every belt here fits standard D section pulleys.
Is it really DX?A DX belt is 32mm wide and 19mm deep. American 8V belts are narrower, at 25mm, and need different pulleys, so measure the width carefully.
Tip: on drives with two or more belts, replace them all at once with a matched set of the same brand, and don't mix smooth and cogged belts on the same drive.
