Bando BX48 Cogged V-belt Bx Section 51 in Outside Length

Product Description

The BANDO BX48 is a classic cogged V-belt in the BX section, designed for power transmission applications across HVAC, industrial, and agricultural equipment. It measures 51 inches in outside length, 48 inches in internal length, and 21/32 inch in width, with a thickness of 13/32 inch. The rubber construction includes cogged inner teeth that increase flexibility and heat dissipation, allowing the belt to run cooler and transfer power more efficiently than a standard wrapped belt. Licensed HVAC technicians and mechanical contractors install this belt on blower assemblies, fan drives, and compressor drives where BX-section sheaves are specified.

The BX48 is suited for residential and light commercial HVAC units, refrigeration systems, and general industrial drive systems that use BX-section pulleys. The cogged profile reduces bending resistance, which is particularly useful on smaller-diameter sheaves common in furnace blower and air handler applications. Its heat-resistant and oil-resistant rubber compound makes it a reliable choice in equipment rooms or mechanical spaces where ambient temperatures and contaminants are a concern.

Compatibility

Designed as a direct replacement for BX48-section V-belts on any drive system specifying a BX-section sheave with a 51 inch outside circumference.

Installation Notes

BX-section V-belts are typically installed by HVAC technicians or mechanical contractors servicing blower, fan, or compressor drive systems. Always de-energize and lock out the equipment before removing or installing a belt. Never pry the belt over a sheave flange under tension; adjust the driven component to relieve tension before seating the belt. Check sheave alignment and tension per the equipment manufacturer's service manual after installation.
