The JASON INDUSTRIAL A99 is a black rubber industrial V-belt measuring 0.5 inches wide by 101 inches in length. Designed for power transmission in industrial drive applications, this belt transfers rotational energy between sheaves and pulleys in mechanical systems found across HVAC equipment, compressors, fans, pumps, and general industrial machinery. The A99 profile follows the standard A-section geometry, making it a direct-fit replacement for worn or failed drive belts in systems that specify A-section sizing. Installation is typically performed by HVAC technicians, millwrights, and industrial maintenance personnel.
This belt is suited for use in residential and light commercial HVAC units, exhaust fans, blower assemblies, and a wide range of industrial drive systems that require a standard A-section V-belt. The A99 designation corresponds to a nominal 101-inch outer circumference with a 0.5-inch top width, matching OEM specifications for equipment calling out A-section belt lengths in that range. Units are sold individually; supplier packaging includes 25 belts per package for shop or fleet stocking.
Designed as an OEM-style replacement for industrial and HVAC drive systems specifying a standard A-section V-belt at 101 inches nominal length.
De-energize and lock out the equipment before removing or installing any drive belt. Relieve drive tension by adjusting the motor mounting plate or tensioner before seating the belt; never force a belt over a sheave under full tension. Verify sheave alignment and groove condition before installing a replacement belt, as worn or misaligned sheaves accelerate belt wear. This work is typically performed by HVAC technicians or industrial maintenance personnel following applicable equipment service procedures.
