Belt type XPB cogged wedge belts
16.3mm wide · 13mm deep · Raw-edge cogged · Multiple leading brands
XPB belts are the cogged version of SPB. 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 on heavier drives.
You’ll find XPB belts on large motors, pumps and compressors, big fans, air handling units and cooling
towers, crushers, sawmills, and industrial and agricultural machinery, and they’re a straight upgrade on a
smooth SPB belt. We stock XPB belts from several leading manufacturers. Search by the code on the old belt,
such as XPB2500, and use the filters to narrow it down by length or brand.

Finding the right XPB belt
Reading the codeXPB2500 means an XPB belt with a 2500mm 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 SPB?An XPB belt runs in the same pulleys as a smooth SPB belt of the same length, so an XPB2500 can usually replace an SPB2500 directly. It’s a simple way to get more life and efficiency from an existing drive.
XPB or BX?An XPB belt is 16.3mm wide and 13mm deep. A cogged classical BX belt looks similar but is shallower, at 11mm, and runs in B 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.
