V-Belts — Classical & Narrow Section Power Transmission
Search classical and narrow section V-belts from Gates, Dayco, Optibelt, Bando, and Continental. Filter by belt section (A, B, C, 3V, 5V, 8V) and length for industrial drive applications.
Key Specification Fields
Belt Section
Classical: A, B, C, D, E. Narrow: 3V, 5V, 8V. Narrow sections carry more power per belt.
Outside Length
Nominal belt circumference — e.g., "B60" is a B-section belt 60" outside length
Type
Standard, Banded (two or more joined for vibration), Cogged (notched for flexibility)
Material
Neoprene, polyester cord, and aramid/Kevlar tensile members for high-performance belts
Common Applications
- Fan drives on motors
- Pump drives
- Compressor drives
- Agricultural and HVAC equipment
- Machine tool spindle drives
Frequently Asked Questions
Classical vs. narrow V-belts — which should I use?
Narrow section belts (3V, 5V, 8V) can transmit 30–50% more power per belt than classical sections (A, B, C) of comparable width, and are preferred for new designs. Classical belts remain dominant for legacy equipment, replacements, and applications where classical sheaves are already installed.
