Bando BX87 Cogged V-belt Bx Section 90 in Ol

Product Description

The BANDO BX87 is a classic cogged V-belt in the BX section, designed for power transmission in HVAC, industrial, and mechanical drive applications. It measures 90 inches outside length with an internal length of 87 inches, a width of 21/32 inches (0.66 inches), and a thickness of 13/32 inches (0.41 inches). The cogged construction reduces bending resistance and heat buildup, improving efficiency and belt life compared to a standard wrapped belt. Made from rubber with heat-resistant and oil-resistant properties, this belt is built to handle demanding environments. Licensed HVAC technicians and mechanical contractors are the primary installers.

The BX87 is suited for residential and light commercial HVAC units, blower drives, fan drives, compressor drives, and general power transmission equipment that accepts BX-section cogged V-belts. The cogged profile allows it to run on smaller-diameter sheaves without sacrificing flex life, making it a practical choice for tight drive configurations commonly found in rooftop units, air handlers, and belt-driven blowers.

Key Features

• BX section cogged construction reduces flex fatigue and heat buildup on smaller sheaves
• 90 inches outside length, 87 inches internal length for accurate replacement sizing
• 21/32 inch (0.66 inch) width and 13/32 inch (0.41 inch) thickness match standard BX-section sheave grooves
• Heat-resistant and oil-resistant rubber compound for demanding drive environments
• Meets ARPM industry standards for V-belt dimensions and performance
• Classic cogged style compatible with standard BX-section fixed and variable-pitch sheaves

Compatibility

Designed as a direct replacement for BX section cogged V-belts with a 90 inch outside length and 21/32 inch width in residential and commercial belt-drive systems.

Installation Notes

Belt replacement is typically performed by a licensed HVAC technician or mechanical technician. Always de-energize and lock out the equipment before removing the old belt or installing the new one. Adjust sheave centers to allow belt installation without forcing the belt over the sheave flange, then tension to the drive manufacturer specification before returning the unit to service. Inspect sheave grooves for wear before installing a replacement belt, as worn grooves accelerate belt degradation.
