Jason Industrial B48 Rubber V-belt 5/8 X 51 Inch

Product Description

The JASON INDUSTRIAL B48 is a rubber V-belt designed for industrial power transmission applications. Measuring 5/8 inch wide by 51 inches in length, this B-section belt delivers reliable torque transfer in demanding drive systems. Manufactured by Megadyne/Jason, the B48 is built from rubber for flexibility and durability under continuous load. It is suited for use on standard B-section sheaves and pulleys found throughout light and heavy industrial equipment. Installation is straightforward for maintenance technicians and millwrights familiar with belt-drive systems.

The B48 fits a wide range of industrial drive applications including HVAC equipment, compressors, fans, pumps, and general-purpose machinery that use B-section belt drives. It is well-suited for both original equipment installations and field replacement on production floors, mechanical rooms, and equipment service environments. The 51-inch pitch length makes it a common replacement size across many standard drive configurations in commercial and industrial settings.

Compatibility

Designed as a standard B-section replacement V-belt for industrial equipment using 5/8 inch B-profile belt drives, including fans, compressors, pumps, and HVAC units requiring a 51-inch belt length.

Installation Notes

Belt replacement should be performed by a qualified technician with the drive system fully de-energized and locked out per OSHA lockout/tagout procedures. Inspect sheaves for wear and proper alignment before installing the new belt. Tension the belt to the equipment manufacturer's specified deflection without over-tightening, which can damage bearings and shorten belt life. Never pry or force a belt onto a sheave using tools that could nick or crack the belt body.
