Jason Industrial BX38 Cogged V-belt

Product Description

The JASON INDUSTRIAL BX38 is a cogged V-belt designed for power transmission applications in industrial and HVAC equipment. Cogged belts feature lateral notches along the inner surface that reduce bending resistance, allowing them to run cooler and more efficiently than standard wrapped V-belts of the same cross-section. The BX designation indicates a heavy-duty B-series profile, and the 38 nominal length code places this belt in a commonly stocked size range for blower drives, fan assemblies, and general-purpose machinery. Licensed trades and maintenance technicians working on belt-driven systems rely on this style of belt for dependable torque transfer across a range of operating speeds.

The BX38 is suited for use in residential and light commercial HVAC systems, specifically in belt-drive air handlers and furnace blower assemblies, as well as in agricultural equipment, compressors, and general industrial machinery. The cogged construction makes it compatible with smaller-diameter sheaves where a standard B-section wrapped belt would experience excessive flex stress. It is a direct replacement for any application specifying a BX38 cogged belt.

Key Features

• Cogged inner surface reduces flex resistance and heat buildup during operation
• B-series cross-section profile for compatibility with standard B-groove sheaves and pulleys
• Nominal 38 length code for fit in common blower and fan drive configurations
• Engineered for higher efficiency compared to standard wrapped V-belts of the same size
• Suitable for belt-drive HVAC blower assemblies, compressors, and industrial equipment

Compatibility

Designed as a direct-fit replacement for any drive system specifying a BX38 cogged V-belt with a standard B-series sheave groove profile.

Installation Notes

Belt replacement should be performed by a qualified HVAC technician or industrial maintenance professional. Always disconnect and lock out electrical power to the unit before removing the belt guard or accessing the drive assembly. Never pry a belt onto a sheave under tension; adjust the motor mount or idler to relieve tension before seating the belt, then re-tension according to the equipment manufacturer's deflection specification. Inspect sheave grooves for wear or misalignment before installing a new belt.
