Bando 3VX750 Cogged V-belt 3VX 75in X 3/8in

Product Description

The BANDO 3VX750 is a narrow cogged V-belt designed for power transmission in industrial and commercial belt-drive applications. Built from rubber with a cogged construction, the 3VX750 reduces bending stress and heat buildup, allowing it to run efficiently on smaller-diameter sheaves. The belt meets ARPM standards and is rated for both heat and oil resistance, making it suitable for demanding drive environments such as HVAC equipment, compressors, fans, and blowers. At 75 inches outside length and 3/8 inch width, it fits the standard 3VX section groove profile.

This belt is commonly used in residential and light commercial HVAC systems, refrigeration units, and general industrial machinery where a narrow section cogged belt is specified. The 3VX section is widely used in fan and blower drives on air handling units, condensing units, and belt-driven compressors. HVAC technicians and mechanical contractors typically replace this belt during scheduled preventive maintenance or when drive efficiency has dropped due to belt wear or glazing.

Key Features

• Cogged construction reduces bending resistance and heat generation on small-diameter sheaves
• Heat resistant and oil resistant rubber compound for demanding drive environments
• Meets ARPM standards for V-belt dimensions and performance
• Narrow 3VX section profile fits standard 3VX-groove sheaves
• Black rubber construction with 75 inches outside length and 3/8 inch belt width

Compatibility

Designed as an OEM-style replacement for any belt-drive application specifying a 3VX section cogged V-belt with a 75 inch outside length and 3/8 inch width groove profile.

Installation Notes

A licensed HVAC technician or qualified mechanical technician should de-energize and lock out the equipment before replacing the belt. Loosen the drive motor mount to relieve belt tension before removal — never force a belt over a sheave flange. After seating the new belt in the sheave grooves, adjust tension per the equipment manufacturer's deflection specification and re-check alignment before returning the unit to service.
