Jason Industrial B70 Rubber V-belt 5/8 X 73 Inch

Product Description

The JASON INDUSTRIAL B70 is a classical rubber V-belt designed for industrial power transmission applications. Measuring 5/8 inch wide by 73 inches in length, this B-section belt delivers reliable torque transfer in demanding drive systems. Constructed from black rubber, it is built to handle the flex fatigue and heat cycling common in continuous-duty industrial equipment. HVAC technicians, millwrights, and maintenance professionals install this belt type on belt-driven fans, blowers, compressors, and pumps where a standard B-section profile is specified.

The B70 is suited for both light commercial and industrial drive applications. It fits belt-driven equipment running open or semi-enclosed drive guards, including fan coil units, air handling units, industrial blowers, and compressor assemblies that call for a B-section classical V-belt in the 73-inch outside circumference range. The 5/8-inch top width is a recognized standard dimension used across a broad range of OEM and aftermarket sheave systems.

Key Features

• Classical B-section profile with 5/8-inch top width for wide sheave compatibility
• 73-inch length suits mid-range center-distance drive configurations
• Black rubber construction resists heat cycling and flex fatigue in continuous-duty service
• Sold in a package of 20 belts, suitable for stocking or fleet maintenance programs

Compatibility

Designed as an OEM-style replacement for industrial and commercial equipment requiring a classical B-section V-belt with a 5/8-inch width and 73-inch length designation.

Installation Notes

Installation should be performed by a qualified technician following the equipment manufacturer's service documentation. Always de-energize and lock out the drive unit before removing or installing belts. Never pry or force a belt over a sheave with a tool; adjust center distance to allow proper seating. After installation, verify belt tension and sheave alignment per standard drive maintenance practice before returning the unit to service.
