Out of stock
Gates Micro-V belts are multi-ribbed (serpentine-profile) industrial belts — a single belt with several parallel small ribs running in a matching grooved pulley, replacing multiple narrow V-belts on one drive. The M section suits industrial multi-ribbed drives across machine tools, conveyors, appliances, outdoor power equipment and medical/exercise equipment. Gates Micro-V belts are stocked by AIMS Industrial for rapid supply across Australia.

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. Looking for an automotive serpentine belt instead? Automotive Micro-V drives use the K section — see our automotive Micro-V range and 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.
