Bando 3VX250 Cogged V-belt 3VX 25 in Od 3/8 in Wide

Product Description

The BANDO 3VX250 is a narrow cogged V-belt designed for power transmission in belt-driven mechanical systems. Built from rubber in the 3VX section profile, it measures 25 inches in outside length, 3/8 inch in width, and 5/16 inch in thickness. The cogged construction reduces bending resistance across the belt cross-section, allowing it to run cooler and flex more efficiently on smaller-diameter sheaves. Heat and oil resistance are built into the compound, extending service life in environments where ambient temperatures and lubricant contamination are common concerns. This belt is installed and replaced by HVAC technicians, millwrights, and equipment service professionals across a wide range of drive applications.

The 3VX250 is suited for use in residential and light commercial HVAC equipment, fans, blowers, compressors, and general industrial machinery where a narrow cogged 3VX-section belt is specified. Its cogged profile makes it compatible with standard 3VX-groove sheaves and pulleys. The belt is particularly useful in high-speed, high-efficiency drives where reduced heat generation and improved flex life are priorities over a standard wrapped belt of the same cross-section.

Key Features

• Narrow cogged 3VX section profile for improved flexibility and reduced heat buildup
• 25 inch outside length suits common blower and fan drive configurations
• Heat-resistant and oil-resistant rubber compound extends service life
• 3/8 inch width and 5/16 inch thickness match standard 3VX sheave groove dimensions
• Meets ARPM standards for dimensional accuracy and performance
• Black rubber construction — no fabric wrap to crack or peel over time

Compatibility

Designed as a direct replacement for any application specifying a 3VX section cogged V-belt with a 25 inch outside length and 3/8 inch width, used with standard 3VX-groove sheaves and pulleys.

Installation Notes

Belt replacement is typically performed by HVAC technicians or mechanical service professionals. Always de-energize and lockout/tagout the equipment before removing drive guards or handling belts. Set sheave spacing to allow belt installation without forcing — never pry a belt onto a sheave, as this can damage the cord structure and shorten belt life. After installation, verify tension and alignment per the equipment manufacturer's drive specifications before returning the unit to service.
