Bando BX124 Cogged V-belt Bx Section 127 in

Product Description

The BANDO BX124 is a classic cogged V-belt in the BX section, designed for power transmission on industrial, HVAC, and agricultural drive systems. It measures 127.0 inches in outside length, 0.66 inches (21/32 inches) in width, and 0.41 inches (13/32 inches) in thickness. The rubber construction features a cogged underside that reduces bending resistance and dissipates heat more effectively than a standard wrapped belt. This belt meets ARPM standards and carries resistance ratings for both heat and oil exposure, making it a dependable choice for demanding drive environments.

The BX124 fits drive systems requiring a BX-section belt with a 127.0-inch outside length and a 124.0-inch internal length. Typical applications include fan drives, blower drives, compressors, pumps, and light industrial machinery where a cogged V-belt profile is specified. The BX section is a common replacement profile for HVAC equipment blower assemblies and packaged rooftop units, as well as general-purpose industrial equipment that calls out a BX-series belt by number.

Compatibility

Designed as an OEM-style replacement for drive systems specifying a BX-section cogged V-belt with a 127.0-inch outside length. Cross-reference your existing belt number BX124 to confirm fitment before installation.

Installation Notes

Belt replacement is typically performed by HVAC technicians, millwrights, or general maintenance mechanics. Always de-energize the drive system and lock out or tag out the power source before removing or installing any belt. Adjust sheave center distance to allow belt seating without prying, then tension to the drive manufacturer's specification using a belt tension gauge. Do not use belt dressing compounds, as these can degrade rubber compounds and reduce belt life.
