Jason Industrial B47 Rubber V-belt 5/8 X 50 Inches

Product Description

The JASON INDUSTRIAL B47 is a black rubber V-belt designed for industrial power transmission applications. Measuring 5/8 inches wide by 50 inches in length, this B-section belt delivers reliable torque transfer in a wide range of drive configurations. It is built from rubber construction suited to withstand the friction, heat, and tension demands common in industrial machinery and HVAC equipment. Maintenance technicians, millwrights, and HVAC service professionals install this belt as a direct replacement or new-install component on belt-driven systems where a standard B-section profile is specified.

The B47 fits drive applications found in commercial and light industrial settings, including fan assemblies, blowers, compressors, pumps, and other rotating equipment that uses a classic B-section V-belt drive. It is well suited for both indoor mechanical rooms and equipment yards where standard fractional-horsepower and medium-duty drives are common. This belt is sold individually and is also available in package quantities of 30 units, making it practical for fleet maintenance and service stocking.

Key Features

• B-section profile: 5/8 inches wide, compatible with standard B-section sheaves and pulleys
• 50-inch nominal outside length for direct B47 specification fitment
• Black rubber construction resists heat, flexing fatigue, and drive tension
• Classic V-belt design ensures positive grip in matched sheave grooves
• Suitable for fan, blower, pump, and compressor drive applications

Compatibility

Designed as an OEM-style replacement for industrial and HVAC equipment requiring a standard B-section V-belt with a 50-inch nominal length.

Installation Notes

B-section V-belts are typically installed by HVAC technicians, millwrights, or maintenance mechanics. Always de-energize and lock out the drive unit before removing or installing a belt. Relieve sheave center distance to seat the belt without prying or forcing it over the sheave flange, which can damage the belt cords. After installation, adjust center distance to achieve proper tension and check alignment before returning the equipment to service.
