Jason Industrial A77 Rubber V-belt 0.5 X 79 Inches

Product Description

The JASON INDUSTRIAL A77 is a black rubber V-belt designed for industrial power transmission applications. Measuring 0.5 inches wide and 79 inches in outer circumference, this A-section belt delivers reliable torque transfer across a wide range of driven equipment. Rubber construction provides flexibility and resilience under continuous load cycling. This belt is a standard A-section profile, making it a common replacement component serviced by maintenance technicians, millwrights, and industrial mechanics in both light and heavy manufacturing environments.

The A77 is suited for use on industrial machinery, HVAC equipment, agricultural implements, pump drives, compressors, and general-purpose power transmission systems that accept A-section V-belt drives. Its standard cross-section profile fits sheaves and pulleys designed to the A-belt specification. This belt is appropriate for both single-belt and banded-drive configurations where the A-section profile is specified by the OEM.

Key Features

• A-section V-belt profile for broad sheave compatibility
• 0.5 x 79 inch dimensions for precise drive sizing
• Black rubber construction for flexibility and durability under load
• Suitable for industrial, HVAC, agricultural, and pump drive applications
• Sold individually; available in package quantities of 25

Compatibility

Designed as an OEM-style replacement for industrial and commercial equipment that specifies an A-section V-belt with a 79-inch nominal length.

Installation Notes

V-belt replacement should be performed by a qualified mechanic or maintenance technician. De-energize and lock out the drive system before removing guards or handling belts. Never pry a belt onto a sheave under tension; always adjust the drive center distance to allow proper belt seating. After installation, check belt tension and sheave alignment per the equipment manufacturer's specifications before returning the drive to service.
