Bando 5VX780 Cogged V-belt 5VX 78 Inch 5/8 Inch Width

Product Description

The BANDO 5VX780 is a narrow cogged V-belt engineered for power transmission in HVAC, industrial, and mechanical drive applications. Built from rubber with a cogged underside, it flexes over smaller-diameter sheaves with less heat buildup than a standard wrapped belt. The 5VX section designation indicates a narrow profile at 5/8 inch wide and 17/32 inch thick, with an outside length of 78 inches. Heat-resistant and oil-resistant construction extends service life in demanding equipment rooms and rooftop unit installations. Licensed HVAC technicians and mechanical contractors use this belt as a direct drive replacement on blower assemblies, compressors, and fan systems.

The 5VX780 fits 5VX-section drive systems commonly found in commercial rooftop units, air handling units, large residential split systems, and industrial belt-drive blowers. The narrow cogged design is suited to high-speed, high-efficiency drives where reduced slippage and improved sheave wrap are critical. Any application calling for a 5VX780 belt or a 5VX section with 78 inches outside circumference is a direct fit candidate.

Key Features

• Cogged underside reduces flex resistance and heat buildup on small-diameter sheaves
• Narrow 5VX section profile improves power transmission efficiency over classical sections
• Heat-resistant and oil-resistant rubber construction for demanding mechanical environments
• 78 inch outside length suits wide sheave center-distance configurations
• Meets ARPM standards for V-belt dimensions and performance
• Black rubber construction with consistent cross-section for balanced drive operation

Compatibility

Designed as a direct replacement for any drive system specifying a 5VX section V-belt with a 78 inch outside length and 5/8 inch belt width per ARPM dimensional standards.

Installation Notes

A qualified HVAC technician or mechanical contractor should perform belt replacement. Disconnect and lock out all power to the unit before removing the belt guard or accessing the drive. Use a belt tension gauge to set proper deflection after installation — do not overtighten, as excess tension accelerates bearing and shaft wear. Never pry a belt over a sheave; always adjust sheave center distance to allow easy seating, then re-tension to specification.
