Bando BX36 Cogged V-belt Bx Section 39 in Ol

Product Description

The BANDO BX36 is a classic cogged V-belt in the BX section, designed for power transmission applications in HVAC, refrigeration, and general industrial equipment. It measures 39 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 flexibility and heat dissipation compared to a standard wrapped belt. Built from rubber with heat-resistant and oil-resistant properties, this belt is intended for installation by HVAC technicians, equipment mechanics, and maintenance professionals working on belt-driven systems.

The BX36 is suited for belt-driven HVAC units including fan coil units, air handlers, condenser fan assemblies, and general mechanical equipment using BX-section sheaves or pulleys. The cogged profile allows use on smaller-diameter pulleys without the flex fatigue common in solid-back belts. It conforms to ARPM standards, making it a recognized industry-standard replacement for BX-section drive applications in both residential and light commercial settings.

Key Features

• Cogged classic V-belt design reduces bending resistance and improves flex life
• Heat-resistant and oil-resistant rubber construction for demanding drive environments
• BX section with 39-inch outside length and 36-inch internal length
• 21/32-inch width and 13/32-inch thickness for proper sheave fit
• Meets ARPM standards for dimensional and performance consistency
• Black rubber finish suitable for indoor and outdoor belt-drive systems

Compatibility

Designed as a standard BX-section cogged V-belt replacement for belt-driven HVAC, refrigeration, and general industrial equipment using BX-profile sheaves or pulleys requiring a 39-inch outside length.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical tradesperson. Disconnect and lock out all power to the unit before removing the old belt or installing the new one. Never pry a belt onto a sheave with a tool; loosen the motor mount to relieve tension before seating the belt, then adjust to the manufacturer-specified deflection. Inspect sheaves for wear or misalignment before installing a replacement belt.
