Belt type XPA cogged wedge belts
12.7mm wide · 10mm deep · Raw-edge cogged · Multiple leading brands
XPA belts are the cogged version of SPA. Notches moulded into the underside let them bend round smaller
pulleys, run cooler and transmit more power, which can cut energy use and extend belt life. You’ll find
XPA belts on larger motors, pumps and compressors, supply and extract fans, air handling units, and
industrial and agricultural machinery, and they’re a straight upgrade on a smooth SPA belt. We stock XPA
belts from several leading manufacturers. Search by the code on the old belt, such as XPA1500, and use the
filters to narrow it down by length or brand.

Finding the right XPA belt
Reading the codeXPA1500 means an XPA belt with a 1500mm datum length (Ld). Wedge belts are almost always sized by datum length in millimetres, which is measured at the belt’s pitch line rather than round the inside or outside.
Upgrading from SPA?An XPA belt runs in the same pulleys as a smooth SPA belt of the same length, so an XPA1500 can usually replace an SPA1500 directly. It’s a simple way to get more life and efficiency from an existing drive.
XPA or AX?An XPA belt is 12.7mm wide and 10mm deep. A cogged classical AX belt looks similar but is shallower, at 8mm, and runs in A section pulleys, so measure the depth to be sure.
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.
