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.
