V-Belt Sheaves & Pulleys — Specifications Database
Search V-belt sheaves from Dodge, TB Wood's, Browning, and other manufacturers. Filter by belt section, groove count, pitch diameter, and bore for belt-driven power transmission systems.
Key Specification Fields
Belt Section
Must match belt section: A/B (combined), C, D; or 3V, 5V, 8V for narrow section
Number of Grooves
1-groove through 8-groove — matches number of belts in drive
Pitch Diameter (OD)
Determines speed ratio; larger diameter = slower speed on driven side
Bore / Bushing
Fixed bore, QD bushing mount, or taper-lock bushing mount
Material
Cast iron (standard), ductile iron, or aluminum (light duty)
Common Applications
- Motor-to-fan drives
- Motor-to-pump drives
- Compressor and blower drives
Frequently Asked Questions
How do I calculate V-belt sheave speed ratio?
Speed ratio = Driver pitch diameter ÷ Driven pitch diameter. Driven speed (RPM) = Driver RPM × (Driver PD ÷ Driven PD). For example, a 6" driver sheave on a 1750 RPM motor driving a 12" driven sheave gives 875 RPM output speed.
