Jason Industrial BX42 V-belt Bx Section Cogged

Product Description

The JASON INDUSTRIAL BX42 is a BX-section cogged V-belt designed for power transmission in HVAC, agricultural, and general industrial drive applications. The cogged construction reduces bending resistance, which allows the belt to run cooler and improves efficiency on smaller-diameter sheaves. BX-section belts are a standard raw-edge, notched profile that provides higher flexibility and grip compared to a conventional wrapped belt. Licensed HVAC technicians and mechanical contractors install this belt type in blower and fan drive assemblies as part of routine preventive maintenance or unscheduled drive repairs.

The BX42 fits drive systems that call for a BX-section belt with an outside circumference of approximately 45 inches, corresponding to the standard BX42 industry designation. It is commonly used in residential and light commercial air handling units, condensing unit fan drives, and general-purpose equipment with fractional to several-horsepower motor drives. Always verify the sheave groove profile and belt cross-section match before installation.

Key Features

• BX-section cogged profile reduces heat buildup and extends belt life on small-diameter sheaves
• Raw-edge construction improves traction and power transfer efficiency
• Standard BX42 industry sizing ensures broad cross-reference compatibility
• Suitable for HVAC blower drives, fan assemblies, and general industrial equipment

Compatibility

Designed as an OEM-style replacement for drive systems specifying a BX-section cogged V-belt in the BX42 size designation.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical contractor. Disconnect and lock out all power to the unit before removing or installing drive belts. Never pry a belt over a sheave under tension; always release drive tension via the motor adjustment slide or tensioner before seating the new belt. After installation, adjust belt tension to the drive manufacturer's specification and verify alignment of all sheaves before restoring power.
