Bando BX79 Cogged V-belt Bx Section 82 in

Product Description

The BANDO BX79 is a classic cogged V-belt engineered for high-load power transmission in commercial and industrial drive applications. Built to BX section dimensions, it measures 82 inches in outside length, 21/32 inch in width, and 13/32 inch in thickness, with a belt pitch of 80.8 inches. The cogged construction reduces bending stress and heat buildup compared to a standard raw-edge belt, allowing operation at higher efficiency across a wide speed range. The rubber compound is rated heat resistant and oil resistant, extending service life in demanding environments. Technicians across HVAC, agricultural, and general mechanical trades specify this belt for fan drives, blowers, pumps, and compressors.

The BX79 fits drives requiring a BX section belt with a 79-inch internal length. It is a direct replacement for any BX79-designated belt in residential and commercial HVAC air handler fan assemblies, package unit blower drives, industrial fan decks, pump drives, and light-duty compressor applications. The cogged profile is compatible with standard BX-section sheaves and does not require modified pulleys. Installers working on equipment with tight drive centers or high-torque startup loads frequently select the cogged BX profile over a smooth classical B-section belt for improved grip and reduced slippage.

Key Features

• BX section cogged profile reduces heat buildup and extends belt life in continuous-duty drives
• Outside length of 82 inches with a belt pitch of 80.8 inches for precise drive sizing
• Width of 21/32 inch and thickness of 13/32 inch match standard BX-section sheave grooves
• Heat-resistant and oil-resistant rubber compound rated for demanding service environments
• Meets ARPM standards for dimensional consistency and power rating
• Classic cogged style fits standard BX pulleys without modification

Compatibility

Designed as a direct-replacement BX section cogged V-belt for any application specifying a BX79 belt. Compatible with standard BX-section sheaves and pulleys. Verify inside circumference, outside length, and section dimensions against the drive specification before installation.

Installation Notes

Belt replacement is typically performed by HVAC technicians, millwrights, or mechanical maintenance personnel. Disconnect and lock out all power to the driven equipment before removing the old belt or installing the new one. Adjust drive center distance to allow belt installation without forcing or rolling the belt onto the sheave, which can damage internal cords. After installation, verify belt tension and alignment per the equipment manufacturer's drive specification before returning the unit to service.
