Bando BX120 Classic Cogged V-belt Bx Section

Product Description

The BANDO BX120 is a classic cogged V-belt designed for power transmission applications across a wide range of industrial and commercial equipment. Built from rubber with a cogged profile, this BX-section belt reduces heat buildup and flexing resistance, allowing it to run cooler and last longer than standard wrapped belts. At 123 inches outside length and 21/32 inch width, it fits drive systems requiring a full-length BX-series belt. It carries an ARPM standards designation and is rated for heat and oil resistance, making it suitable for demanding service environments. HVAC technicians, equipment mechanics, and industrial maintenance pros are the typical installers.

The BX120 is used in residential and commercial HVAC systems, agricultural equipment, industrial machinery, and general power transmission drives where a BX-section cogged belt is specified. The cogged construction improves grip on smaller-diameter sheaves and allows tighter bend radii compared to smooth-back belts. This belt is appropriate for applications where heat resistance and oil resistance are required service conditions, such as equipment rooms, mechanical yards, and rooftop unit fan drives. Always verify sheave groove profile matches the BX belt section before installation.

Key Features

• Cogged profile reduces flexing resistance and heat buildup for longer service life
• Heat resistant and oil resistant rubber construction
• BX section with 123 inches outside length and 21/32 inch belt width
• Meets ARPM standards for V-belt performance and dimensional accuracy
• Classic cogged style fits standard BX-groove sheaves and pulleys
• 0.41 inch thickness provides consistent cross-section for stable power transfer

Compatibility

Designed as an OEM-style replacement for drives specifying a BX-section cogged V-belt with 123 inches outside length and 120 inches internal length.

Installation Notes

Installation should be performed by a qualified mechanic or HVAC technician following equipment manufacturer lockout/tagout procedures. Power down and de-energize the drive system completely before removing the old belt or seating the replacement. Never pry or roll a V-belt onto a sheave under tension; always release drive tension fully before installation. Check sheave alignment and sheave wear before installing the new belt, and re-tension according to the equipment manufacturer specification after installation.
