Belt type XPZ cogged wedge belts
9.7mm wide · 8mm deep · Raw-edge cogged · Multiple leading brands
XPZ belts are the cogged version of SPZ, the most widely used wedge belt. 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 XPZ belts on electric motors, pumps, compressors, fans and air
handling units, and compact industrial drives, and they’re a straight upgrade on a smooth SPZ belt. We
stock XPZ belts from several leading manufacturers. Search by the code on the old belt, such as XPZ1250, and
use the filters to narrow it down by length or brand.

Finding the right XPZ belt
Reading the codeXPZ1250 means an XPZ belt with a 1250mm 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 SPZ?An XPZ belt runs in the same pulleys as a smooth SPZ belt of the same length, so an XPZ1250 can usually replace an SPZ1250 directly. It’s a simple way to get more life and efficiency from an existing drive.
XPZ or ZX?An XPZ belt is 9.7mm wide and 8mm deep. A cogged classical ZX belt looks similar but is shallower, at 6mm, and runs in Z 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.
