The JASON INDUSTRIAL A38 is a classic A-section rubber V-belt designed for industrial power transmission applications. Measuring 1/2 inch in width and 40 inches in length, this belt transfers rotational drive between sheaves and pulleys in a wide range of mechanical systems. The A38 is manufactured from black rubber and follows the standard A-section profile, making it a direct-fit replacement for OEM and aftermarket belt drives. HVAC technicians, industrial maintenance mechanics, and equipment service professionals install this belt on blowers, fans, compressors, and general-purpose drive assemblies where a reliable, cost-effective V-belt is required.
The A38 fits A-section belt drive systems commonly found in commercial and light industrial equipment, including HVAC air handlers, belt-driven blowers, agricultural machinery, and shop equipment. Its standard A-section cross-section dimensions make it interchangeable across a broad range of single-groove and multi-groove sheave configurations. The 40-inch outside circumference suits medium-span drive setups typical of rooftop units, fan coil drives, and standalone belt-driven equipment in both residential and commercial installations.
Designed as an OEM-style replacement for A-section V-belt drive systems requiring an A38 belt designation. Compatible with any sheave or pulley grooved to the standard A-section profile.
A-section V-belts are installed by licensed HVAC technicians and industrial maintenance mechanics. Always de-energize and lock out the equipment before removing or installing any drive belt. Use a belt tension gauge to set proper deflection per the equipment manufacturer's specification after installation. Never pry a belt over a sheave with sharp tools, as this can damage the belt cord and reduce service life.
