Jason Industrial B46 Rubber V-belt 5/8x49 Inch

Product Description

The JASON INDUSTRIAL B46 is a black rubber V-belt designed for industrial power transmission applications. Cut to a 5/8-inch top width and 49-inch outside circumference, this belt transfers rotational force between sheaves and pulleys in a wide range of mechanical drive systems. The rubber construction provides flexibility and durability under continuous load, resisting heat and wear in demanding shop and field environments. Licensed HVAC technicians, millwrights, and maintenance professionals install this belt type as part of scheduled drive maintenance or emergency replacement service.

This V-belt is suited for use in industrial and commercial mechanical drive applications, including fan drives, compressor drives, pump drives, and general power transmission equipment. The B-section profile is one of the most common cross-sections in industrial service, making the B46 a frequent replacement item in facilities maintenance and HVAC equipment rooms. It is compatible with standard B-section sheaves and grooved pulleys found throughout light and medium industrial machinery.

Key Features

• B-section V-belt profile for compatibility with standard industrial sheaves
• 5/8-inch top width with 49-inch outside circumference
• Black rubber construction for heat resistance and flexibility under load
• Suitable for fan, pump, and compressor drive applications
• Designed for continuous-duty industrial power transmission

Compatibility

Designed as an OEM-style replacement for B-section V-belt applications using standard grooved sheaves and pulleys in industrial and commercial drive systems.

Installation Notes

V-belt installation should be performed by a qualified technician following lockout/tagout procedures before servicing any driven equipment. Never pry a belt over a sheave flange; always relieve tension by adjusting the motor mount or belt tensioner before removal and installation. After seating the new belt, tension should be set per the equipment manufacturer's drive specification and verified with a tension gauge. Inspect sheave grooves for wear or damage before installing a replacement belt.
