Jason Industrial B49 Rubber V-belt 5/8x52 Inch

Product Description

The JASON INDUSTRIAL B49 is a black rubber V-belt designed for industrial power transmission applications. Cut to a 5/8-inch top width and 52-inch outside circumference, this belt transfers rotational power between sheaves and pulleys in a wide range of mechanical drive systems. It is manufactured to standard B-section belt dimensions, making it a direct replacement in any drive configuration spec'd for a B49 belt. Rubber construction provides flexibility, heat resistance, and durability under continuous load. Maintenance technicians, millwrights, and HVAC mechanics are the primary installers in commercial and industrial settings.

This belt is suited for use in industrial machinery, HVAC blower assemblies, air compressors, conveyor drives, agricultural equipment, and general-purpose power transmission systems that call for a B-section V-belt. The standard B49 designation follows RMA/MPTA belt sizing conventions, meaning any drive engineered around a B49 profile can accept this belt without modification to sheave geometry.

Key Features

• B-section V-belt profile: 5/8-inch top width, 52-inch nominal length
• Black rubber construction for flexibility and resistance to heat and wear
• Complies with standard RMA/MPTA B-section dimensional specifications
• Suitable for continuous-duty industrial drive applications
• Drop-in replacement for any drive system spec'd for B49 belts

Compatibility

Designed as a standard B49 V-belt replacement for any industrial or commercial drive system engineered to RMA/MPTA B-section specifications, including HVAC blower drives, compressor drives, and general machinery requiring a 5/8-inch by 52-inch V-belt.

Installation Notes

Installation should be performed by a qualified mechanic or HVAC technician with the drive system fully de-energized and locked out per OSHA lockout/tagout procedures. Loosen the motor mount or tensioner to allow belt seating without prying or forcing the belt over sheave flanges, which can cause internal cord damage. After installation, adjust belt tension to the drive manufacturer's specification and verify sheave alignment before re-energizing the system.
