Bando 3V630 Narrow V-belt 3V 63 in Od 3/8 in Width

Product Description

The BANDO 3V630 is a narrow-section V-belt designed for power transmission in industrial and HVAC drive applications. Built from rubber with heat-resistant and oil-resistant properties, this belt fits drive systems where a 3V section profile is specified. The outside length is 63 inches with a belt width of 0.38 inches and a thickness of 0.32 inches. It meets RMA standards and is sold individually. Licensed mechanics, HVAC technicians, and industrial maintenance professionals typically install this style of belt on blower and fan drive assemblies.

The 3V630 is suited for applications requiring a narrow 3V section profile, including residential and light-commercial HVAC air-handling units, refrigeration equipment, and general-purpose industrial machinery. The narrow profile allows higher speed ratios and tighter center distances compared to classical section belts. It is commonly used as a direct replacement on belt-driven blower and condenser fan assemblies where the 3V section drive sheave is already installed.

Key Features

• Narrow 3V section profile for high-speed, close-center drive applications
• 63-inch outside length for accurate sheave fitment
• 0.38-inch width and 0.32-inch thickness for proper groove seating
• Rubber construction with heat-resistant and oil-resistant properties
• Meets RMA industry standards
• Black color for UV stability and visual inspection ease

Compatibility

Designed as an OEM-style replacement for drive systems specifying a 3V section narrow V-belt with a 63-inch outside length.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical maintenance professional. Disconnect and lock out all power to the unit before removing the old belt or installing the new one. Do not pry the belt over sheave flanges with sharp tools, as this can damage the belt cords. After installation, verify belt tension and sheave alignment per the equipment manufacturer's drive design specifications before returning the unit to service.
