Jason Industrial B85 Rubber V-belt 21/32 X 88 Inch

Product Description

The JASON INDUSTRIAL B85 is a rubber V-belt designed for industrial power transmission applications. Measuring 21/32 inches in width and 88 inches in length, this B-section belt transfers rotational power between sheaves and pulleys in mechanical drive systems. It is constructed from black rubber and built to handle the tension and flex cycles common in continuous-duty industrial equipment. HVAC technicians, millwrights, and maintenance mechanics use this belt as a direct replacement or new-installation drive component in belt-driven systems across commercial and light industrial environments.

The B85 fits B-section drive configurations and is suited for use in air handling units, compressors, fans, blowers, pumps, and other belt-driven machinery where a standard B-section belt is specified. It is appropriate for both residential and commercial equipment installations where the drive geometry calls for an 88-inch nominal outside or effective length in the B-section profile. Installers should verify sheave groove geometry and center distance before installation.

Key Features

• B-section profile sized at 21/32 inches wide by 88 inches long
• Black rubber construction for durability and flex resistance in continuous-duty drives
• Designed for standard B-section sheaves and pulleys
• Suitable for fans, blowers, compressors, pumps, and air handling units
• Sold individually (unit of measure: each)

Compatibility

Designed as an OEM-style replacement or service belt for industrial and commercial equipment using standard B-section V-belt drive configurations.

Installation Notes

B-section V-belts are typically installed and serviced by HVAC technicians, maintenance mechanics, or millwrights. De-energize and lock out the equipment before replacing any drive belt. Loosen the drive motor or tensioner to allow belt installation without prying or forcing the belt over sheave flanges, which can damage the belt structure. After installation, set proper belt tension per the equipment manufacturer's specification and check sheave alignment before returning the system to service.
