Four-Band Banded Cogged V-Belt — 3VX Section, 3/8" Wide (4/3VX)
A four-band, 3VX-section banded cogged V-belt built for high-load, multi-groove drives where individual belts would whip, roll over, or jump the sheave under shock or pulsating loads. Four 3VX narrow-wedge cogged belts are joined by a common tie band so they track as a single unit — sharing load evenly, staying seated in the grooves, and running quieter and more stably than loose matched belts. The molded-notch (cogged) underside adds flexibility, runs cooler, and delivers higher efficiency on small-diameter sheaves.
Key specifications
- Cross section: 3VX narrow wedge (per band)
- Top width: 3/8" (9.5 mm) per band
- Nominal depth: ~5/16" (8 mm)

Typical applications
Belt-driven air compressors, industrial fans and blowers, pumps, HVAC air handlers, machine tools, and heavy industrial machinery — anywhere a single belt needs the added stability of a matched, banded four-belt set.
