Overview
The Gates 4/3VX1000 Super HC PowerBand V-Belt (SKU 9388-4100) is a precision-engineered molded notch belt engineered for demanding multi-belt power transmission systems. This four-strand configuration combines a fabric banded cover with molded notches to deliver high horsepower capacity while minimizing bending stress on small-diameter pulleys. The integral tie band keeps multiple belts operating as a single unit with uniform load distribution.
Key Features
- Super HC Molded Notch Design — Reduces bending stress on smaller pulleys; notches enable tight wraps without sacrificing strength or traction
- PowerBand Tie Band — Permanently bonds belts together for lateral rigidity, preventing lateral shift and belt whip on multi-strand drives
- EPDM Rubber Construction — Weather, oil, water, and solvent resistant; meets RMA oil and heat resistance standards
- Wide Operating Range — Works reliably from −65 °F to +250 °F, protecting against cracking and material degradation
- V80 Matching System — Exceeds RMA and ISO belt tolerance standards for more precise matching, even load distribution, and longer belt life
- Heavy-Duty Banded Cover — Fabric outer wrap provides superior abrasion and wear resistance in harsh industrial environments
