The JASON INDUSTRIAL A27 is a classical A-section rubber V-belt designed for industrial power transmission applications. Measuring 0.5 inches wide with a 29-inch outside circumference, this belt transfers rotational power between sheaves and pulleys in a wide range of mechanical drive systems. Constructed from black rubber, it is built to handle the flex cycles and tension demands typical of continuous-duty industrial equipment. Maintenance technicians and mechanical contractors install this belt type on motors, fans, compressors, and other belt-driven machinery where a standard A-section profile is specified.
The A27 V-belt is suited for light to medium industrial drive applications including HVAC equipment, agricultural machinery, shop equipment, and general-purpose power transmission systems. The classical A-section profile fits standard A-groove sheaves and pulleys. This belt is appropriate for both single-belt and multi-belt drive configurations where an A27 designation is called out by the equipment manufacturer or drive design specification.
Designed as an OEM-style replacement or aftermarket V-belt for any drive system specifying a standard A27 classical A-section V-belt profile.
A licensed mechanic or qualified maintenance technician should de-energize and lock out the drive system before replacing any belt. Remove tension from the drive by adjusting the motor mount or tensioner before slipping the old belt off the sheaves. Never pry a V-belt onto a sheave with a tool, as this can damage the belt cords. After seating the new belt, adjust tension according to the equipment manufacturer's deflection specification and check alignment across all sheaves before returning the system to service.
