Jason Industrial B74 V-belt 5/8 X 77 Inch Rubber

Product Description

The JASON INDUSTRIAL B74 is a black rubber V-belt designed for industrial power transmission applications. Cut to a 5/8-inch top width and 77-inch outside circumference, this belt transfers rotational power between sheaves in a wide range of mechanical drive systems. It is built from rubber compound construction suited to handle the flex, heat, and load cycling typical in industrial environments. HVAC technicians, millwrights, and mechanical contractors install this belt type on blower assemblies, compressors, pumps, and other belt-driven equipment where a standard B-section profile is required.

The B74 fits B-section drive applications found in light commercial and industrial settings. Common install scenarios include air handling units, exhaust fans, industrial blowers, and pump drives. The B-section profile is one of the most widely used classical V-belt cross-sections, making this belt a go-to replacement in facilities maintenance and HVAC service work. It is sold individually and available in package quantities of 20 units for stocking needs.

Key Features

• Classical B-section V-belt profile for broad sheave compatibility
• 5/8-inch top width and 77-inch outside circumference
• Black rubber construction handles flex, heat, and continuous load cycling
• Suitable for blowers, compressors, pumps, and other belt-driven industrial equipment
• Available in package quantities of 20 for shop or fleet stocking

Compatibility

Designed as an OEM-style replacement for B-section V-belt drives in industrial and light commercial mechanical systems requiring a 5/8-inch wide, 77-inch belt.

Installation Notes

Installation is typically performed by a qualified HVAC technician or mechanical maintenance professional. Always de-energize and lock out the equipment before removing the old belt or installing the new one. Adjust sheave spacing to relieve tension before removing the worn belt, then seat the new belt fully in the sheave grooves before restoring drive tension. Do not pry or force the belt over sheave flanges, as this can damage the belt cord structure.
