3VX1000 V-Belt

3VX Section V-Belt — Cogged Narrow Wedge Drive Belt

• Top Width: 3/8" (0.375")
• Height / Depth: 5/16" (0.313")
• Construction: Cogged Narrow Wedge — raw-edge with molded notches
• Cogged: Yes
• HP Range: 1/2 – 25 HP
• Minimum Sheave OD: 2.2"
• Length Basis: Outside circumference ÷ 10 (e.g., 3VX1000 = 100.0" OC) | IC = OC − 1"

The 3VX cogged narrow-wedge V-belt combines the high-power 3V wedge profile (3/8" × 5/16") with raw-edge cogged construction for maximum efficiency and flexibility. Molded notches reduce bending stress, allow sheaves as small as 2.2", and improve heat dissipation under high-duty cycles. Up to 30% more efficient than equivalent classical belts — the preferred choice for energy-efficient HVAC systems, compressors, and high-cycle industrial drives requiring smaller sheaves.
