Gates XPB1000/5VX398 QuadPower 4 Notch

Gates QuadPower 4 XPB section is the fourth-generation cogged narrow V-belt, featuring aramid tensile cord and a notched underside for superior flex efficiency on smaller sheave diameters. It delivers higher power capacity than a standard wrapped belt of the same section and replaces Super HC belts directly.

Where this product is used

Gates V-belts cover the full range of industrial, agricultural and automotive drive applications. Common end uses include:

• Industrial drive systems — air compressors, pumps, fans, blowers and generators across manufacturing and utilities
• Agricultural machinery including combine harvesters, grain augers, irrigation pumps and crop-processing equipment
• HVAC and refrigeration plant — chillers, cooling towers, air handlers and refrigeration compressors

Key specifications

Selecting the right option

Select by belt section first, then by pitch length. Classical sections run A, B, C, D, E (or Z in metric) — cross-reference to the metric ISO equivalent (13A, 17A, 22A) where needed. Narrow sections (3V/SPA, 5V/SPB, 8V/SPC) carry more power in the same envelope. The XP series (XPZ/XPA/XPB/XPC) are notched versions for improved flex efficiency. Gates PowerBand banded belts join multiple strands — specify these for long centre distances, vertical drives or where belt whip is an issue. For Micro-V (K/J section) automotive belts, match by OE reference or by rib count and pitch length. When in doubt, call AIMS — power transmission is our specialty and we'll confirm the right cross-reference.
