Jason Industrial B35 V-belt 5/8 X 38 Inch Black Rubber

Product Description

The JASON INDUSTRIAL B35 is a B-section rubber V-belt designed for industrial power transmission applications. Measuring 5/8 inch wide with a 38-inch outside circumference, it transfers rotational power between sheaves on motors, fans, blowers, compressors, and other belt-driven equipment. The black rubber construction handles the flex, heat, and friction demands of continuous-duty industrial service. HVAC technicians, industrial mechanics, and equipment service technicians install this belt as a direct replacement on belt-driven systems where a standard B35 cross-section is specified.

This belt fits a wide range of belt-driven HVAC and industrial equipment including rooftop units, air handlers, exhaust fans, centrifugal blowers, and general-purpose motor-driven machinery. It is suited for both light commercial and industrial installations where a B-section V-belt is the OEM-specified drive component. The B35 designation is a standard industry cross-section and length classification recognized across multiple equipment manufacturers and drive systems.

Key Features

• B-section profile: 5/8 inch wide, compatible with standard B-groove sheaves
• 38-inch outside circumference for correct tensioning on B35-spec drive systems
• Black rubber construction resists heat, flex fatigue, and wear in continuous-duty service
• Standard B35 industry designation ensures broad cross-reference compatibility
• Sold individually; packaged in quantities of 30 per case

Compatibility

Designed as an OEM-style replacement for belt-driven equipment requiring a standard B-section V-belt with a 38-inch outside circumference.

Installation Notes

Installation is performed by HVAC technicians or industrial mechanics. Disconnect and lock out all electrical power to the equipment before removing the belt guard or accessing drive components. Loosen motor mounting bolts to relieve tension before removing the old belt; never force a belt over sheave flanges under tension. After seating the new belt, adjust motor position to achieve proper belt tension per the equipment manufacturer's specifications before securing fasteners and reinstalling the belt guard.
