J‑Section Poly‑V Belts
J‑Section Poly‑V belts are designed for compact, high‑speed and high‑torque power transmission where smooth running, flexibility and efficiency are essential. Their multi‑ribbed design provides excellent grip, reduced vibration and reliable performance, even on small pulley diameters and high‑speed drive systems.
At Transpower Drives, all J‑Section Poly‑V belts are supplied per rib, giving you complete control over the exact belt width required for your application. This makes them ideal for OEMs, maintenance teams and engineers who need precise sizing and consistent performance.
Dual Part‑Number System (Important)
Each J‑Section Poly‑V belt is listed with two-part numbers:
- The first number is the imperial belt length in inches
- The second number is the metric belt length in millimetres
For example: 130J / 330J = 13 inches long and 330mm long
This dual‑number format ensures compatibility with both imperial‑based machinery and metric‑based equipment, making belt identification faster and more accurate.
J‑Section Poly‑V belts are widely used in:
- Industrial machinery – blowers, pumps, compressors
- Machine tools – grinders, drills, milling machines
- Fitness equipment – treadmills, cross‑trainers
- Home appliances – dryers, grinders, mixers
- Packaging and printing machinery
