Jason Industrial A57 Rubber V-belt 1/2 X 59 Inch

Product Description

The JASON INDUSTRIAL A57 is a classical A-section rubber V-belt designed for industrial power transmission applications. Measuring 1/2 inch wide by 59 inches in length, this belt transfers rotational power between sheaves and pulleys in a wide range of mechanical drive systems. The A57 designation follows standard classical V-belt sizing, making it a direct fit wherever an A-section belt of this length is specified. Licensed HVAC technicians, equipment mechanics, and industrial maintenance professionals install this belt type as part of routine drive maintenance on motors, fans, compressors, and similar rotating equipment.

This belt is suited for light-to-medium duty industrial and commercial drive applications where a classical A-section profile is required. Common install scenarios include blower assemblies, pump drives, agricultural equipment, and general-purpose machinery. The A57 is sold in package quantities of 50 units, making it practical for distributors, service fleets, and maintenance shops that stock belts for recurring replacement needs.

Key Features

• Classical A-section profile for broad sheave compatibility across standard A-groove pulleys
• 1/2 inch top width by 59 inch effective length per standard A-belt sizing conventions
• Black rubber construction for durability and oil resistance in industrial environments
• Sold in quantities of 50 per package, suitable for stocking programs and fleet maintenance
• Manufactured by Megadyne/Jason Industrial for consistent dimensional accuracy

Compatibility

Designed as a standard classical A-section V-belt replacement for industrial and commercial drive systems requiring a 1/2 inch wide, 59 inch length A-profile belt across standard A-groove sheaves and pulleys.

Installation Notes

Installation is performed by qualified mechanical or HVAC technicians. Always de-energize and lock out the drive system before removing or installing belts. Adjust sheave spacing to allow belt installation without forcing the belt over pulley flanges, then tension according to the equipment manufacturer's deflection specification. Inspect sheave grooves for wear before installing a new belt to avoid premature failure.
