Jason Industrial AX39 Cogged V-belt Drive Belt

Product Description

The JASON INDUSTRIAL AX39 is a cogged V-belt designed for use in industrial and commercial power transmission drives. The AX-series designation identifies this as a notched, or cogged, raw-edge V-belt, which reduces bending resistance and heat buildup compared to standard wrapped belts. This belt is installed by HVAC technicians, millwrights, and equipment service professionals wherever an AX39-size cogged V-belt is specified. Its compact cross-section and cogged profile make it well suited for drives with smaller sheave diameters that demand flexibility and efficiency.

The AX39 fits a wide range of light-duty to medium-duty power transmission applications, including HVAC blower drives, compressor drives, and general equipment drives that call for an AX-series belt. The AX designation indicates a top width of approximately 0.5 inches with a cogged underside, and the 39 suffix reflects the effective outside length in the AX sizing convention. This belt is a common replacement in residential and light commercial equipment service.

Key Features

• Cogged, notched underside reduces bending resistance and heat buildup on small-diameter sheaves
• AX-series cross-section profile for compatibility with standard AX-groove sheaves and pulleys
• Raw-edge construction improves power transfer efficiency compared to wrapped belt designs
• Suitable for HVAC blower drives, compressor drives, and general industrial power transmission
• Sized to AX39 industry-standard dimensions for direct cross-reference replacement

Compatibility

Designed as a direct replacement for any drive requiring an AX39-size cogged V-belt with a standard AX-series sheave groove profile.

Installation Notes

Belt replacement should be performed by a qualified technician. Always de-energize and lock out the equipment before removing or installing drive belts. Never force a belt over a sheave flange; adjust the drive to allow slack for installation, then tension per the equipment manufacturer specification. Inspect sheave grooves for wear before installing a new belt.
