Bando BX74 Cogged V-belt Bx Section 77 in Outside Length

Product Description

The BANDO BX74 is a classic cogged V-belt in the BX section, designed for industrial and commercial power transmission applications. It measures 77 inches in outside length with a 21/32 inch width and 13/32 inch thickness, and weighs 1.133 pounds. The cogged profile reduces bending resistance, which lowers heat buildup and improves efficiency compared to standard wrapped belts. The rubber construction includes heat resistance and oil resistance, making it suitable for demanding drive environments. HVAC technicians, mechanical contractors, and maintenance professionals install this belt on blower, fan, and compressor drives.

The BX74 fits belt-driven equipment that specifies a BX section cogged belt with a 74 inch internal length (77 inch outside length). Typical applications include air handling unit blower drives, condenser fan assemblies, industrial fan drives, and general power transmission setups in commercial and light industrial settings. This belt meets ARPM standards and is suited for installations where heat or oil exposure is a concern. Always verify the required belt section and length against the equipment nameplate or drive design specifications before installation.

Key Features

• ARPM standards compliance for consistent performance in industrial applications
• Classic black rubber construction with 77 inch outside length and 74 inch internal length
• 13/32 inch thickness and 21/32 inch width for proper sheave seating

Compatibility

Designed as a direct replacement for any drive specifying a BX74 or BX section cogged V-belt with a 77 inch outside length and 21/32 inch belt width.

Installation Notes

Installation is typically performed by HVAC technicians or mechanical maintenance personnel. Power down and lock out the equipment before removing or installing belts. Adjust drive sheave alignment and belt tension to manufacturer drive specifications after installation. Do not use belt dressing compounds on cogged or rubber V-belts, as these can degrade the rubber and reduce service life.
