Bando BX37 Cogged V-belt Bx Section 40 in

Product Description

The BANDO BX37 is a classic cogged V-belt in the BX section, designed for reliable power transmission in HVAC, agricultural, industrial, and commercial equipment applications. Built from heat-resistant and oil-resistant rubber, this belt measures 40 inches in outside length with a 21/32-inch width and a 13/32-inch thickness. The cogged construction reduces bending resistance, allowing the belt to run cooler and deliver efficient power transfer across a range of drive configurations. ARPM standards compliance ensures dimensional consistency for drop-in replacement installations.

The BX37 is suited for use in air handlers, blower assemblies, compressors, fans, pumps, and general power transmission drives where a BX-section cogged belt is specified. It is a common replacement belt in light commercial and residential HVAC systems as well as industrial machinery requiring a 37-inch internal length drive belt. The black rubber construction handles moderate heat and incidental oil exposure encountered in equipment rooms and mechanical spaces.

Installation Notes

Installation is typically performed by HVAC technicians or mechanical equipment service personnel. Always de-energize and lock out the equipment before removing or installing drive belts. Adjust drive sheave alignment and belt tension according to the equipment manufacturer specifications before returning the unit to service. Do not use belt dressing compounds on cogged rubber belts, as these can degrade the rubber and reduce belt life.
