Jason Industrial B77 Rubber V-belt 5/8 X 80 in

Product Description

The JASON INDUSTRIAL B77 is a rubber V-belt designed for industrial power transmission applications. Cut to a 5/8-inch top width and 80-inch outer circumference, this B-section belt transfers rotational power between sheaves in a wide range of mechanical drive systems. The black rubber construction resists common shop-floor conditions including heat, oil mist, and moderate flexing stress. HVAC technicians, millwrights, and maintenance mechanics install this belt type on fan drives, blower assemblies, compressor drives, and pump systems where a standard B-section profile is specified.

The B77 fits drive systems that call for a B-section V-belt with an 80-inch outer circumference. Typical applications include commercial and light industrial HVAC blower drives, agricultural equipment, shop equipment such as lathes and band saws, and general-purpose machinery where a classical B-section profile is the OEM-specified standard. The belt is sold individually and is packaged in units of 20 for shop or fleet stocking.

Key Features

• Classical B-section profile, 5/8-inch top width, 80-inch outer circumference
• Black rubber construction for durability under heat and flex cycling
• Suitable for fan drives, blower assemblies, compressor drives, and pump systems
• Standard B-section geometry fits widely available matching sheaves and pulleys
• Sold per each; available in a package quantity of 20 for stocking orders

Compatibility

Designed as an OEM-style replacement for industrial and commercial drive systems requiring a classical B-section V-belt with an 80-inch outer circumference.

Installation Notes

De-energize and lock out the drive system before removing the worn belt or installing the replacement. A millwright, HVAC technician, or qualified maintenance mechanic should verify sheave alignment and groove condition prior to installation. Adjust drive tension according to the equipment manufacturer's specification after seating the belt; do not pry the belt over sheave flanges with tools, as this can damage the cord line. Allow a brief run-in period and recheck tension.
