A V-belt is a belt with a trapezoidal (V-shaped) cross-section, designed to fit into the V-grooves of pulleys. The V-shape enhances friction and prevents slippage, making them more efficient in power transmission compared to flat belts.
🔧 Fenner V-Belt Features
Fenner offers different types of V-belts under various brand names. Key features generally include:
High strength and durability
Oil and heat resistance
Antistatic properties (compliant with ISO standards)
Precision engineered for consistent performance
Reduced maintenance with longer service life
📂 Types of Fenner V-Belts
Fenner Classical V-Belts (FHP, A, B, C, D, E Sections)
Standard V-belts used in many industrial applications.
Made from high-quality rubber and polyester cord.
Fenner Wedge V-Belts (SPZ, SPA, SPB, SPC)
Narrower and deeper than classical belts.
Provide higher power transmission in compact drives.
Improved efficiency and reduced space requirements.
Fenner Hexagonal (Double) V-Belts
Used in serpentine drives where the belt needs to drive multiple pulleys in different directions.
Fenner Cogged/Raw Edge Belts
Grooved or notched belts for improved flexibility and heat dissipation.
Better suited for smaller pulley diameters.
Fenner Poly-V Belts (Micro-V belts)
Multi-rib belts used in high-speed, compact applications.
📊 Comparison: Classical vs. Wedge V-Belts
Feature Classical V-Belts Wedge V-Belts
Cross-section shape Wider, shallower Narrower, deeper
Power transmission Moderate Higher (up to 1.5x)
Space efficiency Lower Higher
Heat generation More Less
🏭 Applications
HVAC systems (fans, blowers)
Agricultural machinery
Machine tools
Compressors and pumps
Conveyors
Automotive engines (older models)

📐 Belt Size Designation Example
A V-belt size may be listed as:
SPA 1500
'SPA' refers to the profile type (wedge belt)
'1500' refers to the belt's inside length in millimeters
