Bando BX73 Cogged V-belt Bx Section 76 in Outside Length

Product Description

The BANDO BX73 is a classic cogged V-belt in the BX section, designed for power transmission applications across industrial, HVAC, and mechanical drive systems. It measures 76 inches outside length with a 21/32 inch (0.66 inch) width and 13/32 inch (0.41 inch) thickness. The cogged construction reduces bending resistance, which improves efficiency and lowers operating temperatures compared to standard wrapped belts. Built from rubber with heat-resistant and oil-resistant properties, the BX73 is suited for demanding drive environments where belt life and consistent power transfer matter. Technicians and mechanics install this belt as a direct replacement or OEM-equivalent in belt-driven equipment.

The BX73 fits drive systems requiring a BX-section cogged belt with a 73-inch internal length and 74.80 mm belt pitch. Typical applications include belt-driven HVAC air handlers, refrigeration condensing units, compressors, fans, blowers, pumps, and general industrial machinery. The cogged profile makes it compatible with standard BX-section sheaves and pulleys. It is appropriate for both light commercial and residential equipment where a BX-profile belt is specified by the equipment manufacturer.

Key Features

• Heat-resistant and oil-resistant rubber construction for durability in demanding environments
• 76 inch outside length with 73 inch internal length for accurate drive sizing
• Belt pitch of 74.80 mm ensures consistent engagement with standard BX sheaves
• Meets ARPM standards for V-belt dimensions and performance
• Classic cogged style compatible with standard BX-section variable-speed and fixed-center drives

Compatibility

Designed as an OEM-style replacement for equipment requiring a BX-section cogged V-belt with a 76 inch outside length and 21/32 inch belt width.

Installation Notes

Belt replacement should be performed by a qualified technician with the drive system fully de-energized and locked out per OSHA lockout/tagout procedures. Never pry or force the belt over sheave flanges; always release drive tension before installation and re-tension according to the equipment manufacturer specifications. Inspect sheaves and pulleys for wear or misalignment before installing a new belt, as worn or misaligned sheaves will shorten belt service life significantly.
