Gates AP31 (9185-0031) Predator Classical
Available
The Gates Predator A section is a premium narrow V-belt designed for the most demanding industrial drives. Predator belts deliver higher power ratings in the same drive envelope as standard belts, reducing the number of belt strands required and cutting drive operating costs.
Where this product is used
Gates V-belts cover the full range of industrial, agricultural and automotive drive applications. Common end uses include:
- Mining, quarrying and heavy construction plant subject to pulsating or heavy shock loads — crushers, screens and conveyors
- Agriculture and forestry, including wood processing machinery
- Oil field equipment and sand/gravel operations
Key specifications
| Specification | Detail |
|---|---|
| Belt Section | AP / BP / CP |
| Series | Predator — Gates’ heavy-duty, wrapped aramid-cord V-belt; up to 2.2x the power density of a standard V-belt in the same drive envelope |
| Construction | Wrapped, aramid-cord V-belt. Flex-bonded aramid tensile cords are pound-for-pound stronger than steel and combine limited stretch with extraordinary strength and durability, giving roughly half the stretch of a standard polyester-cord Gates belt for markedly higher power density and easy handling of shock loads. Double-layer bareback cover protects against slippage and punctures, resists debris, and allows the belt to slip under extreme shock-load conditions without excessive heat buildup, prolonging belt life. Gates Curves profile gives proper cord support and full contact with the sheave groove for equal loading, uniform wear and increased belt life. Premium rubber compound; non-self-igniting. |
| Nominal Dimensions (Width x Height) | AP: 13 x 8 mm · BP: 17 x 11 mm · CP: 22 x 14 mm |
| Temperature Range | -35°C to +80°C |
| Performance | Up to 2.2x more power than a standard V-belt of the same section; up to 67% reduced drive width; up to 50% reduced drive weight; up to 35% reduced drive cost versus a standard-belt drive of equivalent power; no increase in shaft load; reduces overhung loads; lets a standard SPB/SPC pulley replace a costly made-to-order 8V belt-drive pulley (Gates) |
| Belt Matching | Predator V-belts must be ordered in matched sets (Gates). Aramid tensile cords have roughly half the stretch of a standard polyester-cord belt, so Predator belts do not run in and equalise tension the way conventional belts do — for any multi-belt drive (2 or more strands on the same pulley), order a Gates-matched set and do not mix individually-ordered Predator belts on one drive. Contact AIMS to order a matched set for multi-belt applications. |
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? 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.
