Jason Industrial B40 Rubber V-belt 5/8 X 43 Inch

Product Description

The JASON INDUSTRIAL B40 is a black rubber V-belt designed for industrial power transmission applications. Measuring 5/8 inch wide by 43 inches in length, this B-section belt transfers rotational drive force between pulleys in a wide range of mechanical systems. It is constructed from rubber for flexibility, heat resistance, and durability under continuous load. HVAC technicians, millwrights, and maintenance professionals install this belt on blowers, fans, compressors, and other belt-driven equipment where a standard B-section profile is specified.

The B40 is suited for both light commercial and industrial drive systems that require a B-section V-belt. Typical applications include air handling units, industrial fans, pump drives, and compressor assemblies. The 5/8 inch top width and 43 inch pitch length match standard B-section pulley grooves. It is sold individually and is available in case quantities of 30 units, making it practical for stocking in service vans or maintenance shops.

Key Features

• B-section profile with 5/8 inch top width fits standard B-groove sheaves
• 43 inch pitch length for direct replacement in B40-specified drive systems
• Black rubber construction resists heat, flex fatigue, and oil splash
• Consistent cross-section geometry reduces vibration and belt slip
• Available in case quantity of 30 for shop or fleet stocking

Compatibility

Designed as an OEM-style replacement for industrial and commercial equipment requiring a standard B-section V-belt with a 43 inch pitch length.

Installation Notes

B-section V-belts are typically installed by HVAC technicians, maintenance mechanics, or millwrights. Always de-energize and lock out the equipment before removing the old belt or installing a new one. Use a belt tension gauge when available to set proper deflection per the equipment manufacturer's specification. Never force a belt onto a sheave with a pry bar, as this can damage the belt cords and shorten service life.
