Jason Industrial MXV4-550 Kevlar V-belt 1/2x55 in

Product Description

The JASON INDUSTRIAL MXV4-550 is a Kevlar-reinforced V-belt measuring 1/2 inch wide by 55 inches in length. Kevlar cord construction delivers higher tensile strength and greater resistance to stretching compared to standard rubber belts, making it well suited for drives that experience shock loads, frequent starts, or variable torque demands. This belt is designed for use in outdoor power equipment applications where durability and dimensional stability under load are critical. Installation is handled by equipment technicians and small-engine service professionals familiar with drive belt replacement on outdoor power units.

The MXV4-550 is sized and constructed for farm, lawn, and garden equipment applications. Typical installations include walk-behind mowers, riding tractors, tillers, and other PTO-driven or blade-drive systems that spec a 1/2-inch classical or fractional V-belt cross section. The Kevlar tensile cord resists heat buildup and maintains belt length over extended service intervals, reducing replacement frequency in high-cycle-count seasonal applications.

Key Features

• Kevlar tensile cord construction for high strength and low stretch
• 1/2 inch top width by 55 inches outside circumference
• Suitable for shock-load and variable-torque drive systems
• Designed for farm, lawn, and garden equipment service
• Resists heat-related elongation for extended service life

Compatibility

Designed as an OEM-style replacement V-belt for farm, lawn, and garden equipment specifying a 1/2-inch by 55-inch Kevlar or MXV-series drive belt.

Installation Notes

Belt replacement is performed by small-engine technicians and equipment service professionals. Disengage all blades, shut off the engine, and remove the ignition key before beginning any belt service. Relieve drive tension using the manufacturer-specified idler or tensioner procedure before removing the worn belt, and inspect all pulleys for wear, misalignment, or debris buildup prior to installing the new belt. Do not pry the belt over pulley flanges with sharp tools, as this can damage the Kevlar cord.
