Gates Powerband - RMA - Narrow Section
Available
The Gates Super HC PowerBand Drive Belt 3VX section delivers high-power, high-efficiency transmission for demanding industrial drives. The cogged underside reduces operating temperature on smaller sheave diameters, extending belt life and improving drive efficiency compared to equivalent wrapped V-belts of the same section.
Where this product is used
Gates Drive Belts are engineered for high-power industrial, agricultural and heavy-duty applications. Typical end uses include:
- High-power industrial drives on mills, crushers, mining conveyors and heavy-duty process equipment
- Agricultural and construction machinery subject to shock loads, vibration and variable torque demands
- Quarrying and material-handling systems where superior power ratings and extended belt life are critical
Key specifications
| Specification | Detail |
|---|---|
| Belt Section | 3VX |
| Series | Super HC Molded Notch PowerBand — Super HC Molded Notch belts joined into a matched multi-rib set with a tie band |
| Construction | Raw edge, moulded-notch (cogged) construction. Gates’ current stock system lists this as Super HC Molded Notch (RMA-coded 3VX/5VX/8VX) — the same notched, raw-edge belt as the ISO-coded Quad-Power 4 (XPZ/XPA/XPB/XPC) range; Gates cross-references the two codes against the same physical belt. Exclusive EPDM compound; precision-ground sidewalls for uniform wedging action; Flex-Bonded polyester tensile cords; double Flex-Weave textile backing; non-self-igniting; static conductive (ISO 1813 & RMA IP3-3). Single strands joined with a tie band (PowerBand) to keep the set matched as one unit. |
| Rib Pitch | 10.32 mm |
| Nominal Dimensions (Width x Height, per rib) | 10 x 8 mm |
| Ribs | 3 |
| Belt Length | 106.0 in effective length (RMA code) |
| Temperature Range | -57°C to +121°C |
| Belt Matching | Meets Gates UNISET tolerances — any belt of the same section and length matches any other; no belt-matching required. |
Selecting the right option
Select by section designation: XPZ (10 mm top, lightest duty), XPA, XPB, XPC (widest, highest power). QuadPower 4 XP belts are direct replacements for standard narrow V-belts of the same section and length — the cogged underside allows operation on smaller sheave diameters than wrapped equivalents. Confirm the published minimum sheave diameter for your section before fitting. For Tri-Power AX/BX/CX cogged classical belts, cross-reference the A/B/C pitch length. Contact AIMS if you need a power-rating check for your specific drive.
