Bando BX33 Cogged V-belt Bx Section 36 in

Product Description

The BANDO BX33 is a classic cogged V-belt in the BX section, designed for power transmission applications across HVAC, refrigeration, and general industrial equipment. It features a 36-inch outside length and a 21/32-inch (0.66 inch) belt width, with a cogged underside profile that reduces bending resistance, runs cooler, and improves grip on smaller sheaves. Constructed from rubber, the BX33 carries heat-resistant and oil-resistant properties, making it suitable for mechanical drive environments where thermal cycling and minor fluid exposure are common. Licensed HVAC technicians and mechanical contractors install this belt as part of blower and fan drive assemblies.

The BX33 fits blower drive, condenser fan, and auxiliary equipment drive applications in residential and light commercial HVAC systems. The cogged design makes it compatible with smaller-diameter sheaves common in direct-drive and belt-drive air handlers, rooftop units, and condensing units. Its ARPM-standard construction ensures dimensional consistency across OEM and aftermarket sheave pairings.

Key Features

• BX section cogged profile reduces heat buildup and increases flexibility over small sheaves
• 36-inch outside length with 33-inch internal length for precise drive sizing
• 21/32-inch width (0.66 inch) and 13/32-inch thickness (0.41 inch) per ARPM standards
• Heat-resistant and oil-resistant rubber construction for demanding mechanical environments
• Classic cogged style compatible with standard BX-section sheaves and pulleys
• ARPM-standard dimensions ensure interchangeability with OEM and aftermarket drives

Compatibility

Designed as an OEM-style replacement for BX-section cogged V-belt drive systems. Dimensionally conforms to ARPM standards for BX33 belts, ensuring fitment with any correctly sized BX-section sheave or pulley.

Installation Notes

This belt is installed by HVAC technicians or mechanical contractors servicing blower or fan drive assemblies. Disconnect and lock out power to the unit before removing the old belt or adjusting sheave spacing. Use proper belt tension procedures per the equipment manufacturer's service manual — do not pry the belt over sheave flanges with tools, as this can cause internal cord damage. Inspect sheave grooves for wear before installing a new belt.
