Bando BX47 Cogged V-belt Bx Section 42 in Outside Length

Product Description

The BANDO BX47 is a classic cogged V-belt in BX section, designed for power transmission in HVAC, industrial, and mechanical drive applications. It measures 42.0 inches outside length with a 1/2 inch top width and 13/32 inch thickness. The cogged profile reduces bending resistance, which improves flexibility and heat dissipation compared to a standard wrapped belt. Constructed from rubber with heat-resistant and oil-resistant properties, this belt is built to handle the thermal and chemical demands typical of blower and fan drive systems. It installs on standard BX-section sheaves and is handled by HVAC technicians, maintenance mechanics, and equipment service professionals.

This belt fits residential and light commercial HVAC systems, agricultural equipment, compressors, and general-purpose drive systems that call for a BX-section cogged belt. The BX47 designation corresponds to a 47.0 inch internal length, which is the standard industry sizing reference for this belt family. It is a common replacement belt for air handler blower drives, condenser fan drives, and similar belt-driven equipment where heat buildup and flex fatigue are primary wear factors.

Key Features

• Cogged construction reduces bending resistance and extends belt life on small-diameter sheaves
• Heat-resistant and oil-resistant rubber compound suits HVAC and mechanical drive environments
• BX section with 1/2 inch top width and 13/32 inch thickness for consistent sheave fit
• 42.0 inch outside length with 47.0 inch internal length for accurate replacement sizing
• Meets ARPM industry standards for V-belt dimensions and performance
• Classic cogged style compatible with standard BX-section variable-speed and fixed-pitch sheaves

Compatibility

Designed as an OEM-style replacement for any drive system specifying a BX-section cogged V-belt with a 47.0 inch internal length. Refer to the equipment nameplate or existing belt markings to confirm BX section before installation.

Installation Notes

A licensed HVAC technician or qualified mechanic should de-energize the equipment and lock out the power source before replacing a drive belt. Loosen the motor mounting bolts to release belt tension before removal; never pry or roll a cogged belt over a sheave under tension. After seating the new belt, adjust motor position to achieve proper tension per the equipment manufacturer specification, then verify sheave alignment with a straightedge before returning the unit to service.
