Jason Industrial B42 Rubber V-belt 5/8x45 Inch

Product Description

The JASON INDUSTRIAL B42 is a black rubber V-belt designed for industrial power transmission applications. Manufactured to B-section standards, it measures 5/8 inch wide with a 45-inch outside circumference, making it a direct-fit replacement in a wide range of drive systems. This belt transfers rotational power between sheaves on motors, fans, compressors, pumps, and other belt-driven equipment. HVAC technicians, industrial maintenance mechanics, and equipment service professionals install this belt during scheduled maintenance or when a worn or cracked belt causes drive slippage or failure. Rubber construction provides reliable grip and flexibility across typical operating temperature ranges found in commercial and industrial environments.

The B42 is suited for residential and light commercial HVAC equipment, industrial machinery, agricultural equipment, and general-purpose drive applications where a standard B-section V-belt is specified. It fits belt-driven blower assemblies, air handlers, condensing units, and motor-to-shaft drive trains that call for a 5/8-inch section belt. Installers should verify the driven sheave groove profile matches the B-section geometry before installation.

Key Features

Compatibility

Designed as an OEM-style replacement for industrial and HVAC equipment requiring a standard B-section V-belt with a 5/8-inch width and 45-inch outside circumference.

Installation Notes

A licensed HVAC technician or qualified maintenance mechanic should install this belt. Disconnect and lock out electrical power to the drive motor before removing the old belt or fitting the new one. Adjust motor mount or belt tensioner to achieve proper deflection per the equipment manufacturer's specification before returning the unit to service. Do not pry the belt over sheave flanges, as this can cause internal cord damage and premature failure.
