D section belts are made for very heavy, high-power drives, such as crushers, mills and quarry plant, large compressors and pumps, big industrial fans, sawmills and heavy agricultural machinery. We stock D section belts from several leading manufacturers, so you can choose the right balance of performance and price for your drive. Search by the code on the old belt, such as D180, and use the filters to narrow it down by length or brand.

Finding the right D section belt

Reading the codeD180 means a D section belt with a 180 inch inside length (4572mm). Metric sizes may show the inside length (Li) or the datum length (Ld), which on D section is 75mm longer, so check which your belt uses.

Which brand?Every belt here fits the same D section pulleys. Choose Optibelt for the longest life on hard-working or continuous drives, or a value brand for occasional-use machinery.

Is it really D section?A D section belt is 32mm wide and 19mm deep. Belts this size are often banded on heavy drives, and American 8V belts are narrower, at 25mm, so measure carefully.

Tip: on drives with two or more belts, replace them all at once with a matched set of the same brand. For small pulleys or hot-running drives, a cogged DX belt of the same length is a straight upgrade.
