Jason Industrial B66 Rubber V-belt 5/8 X 69 Inch

Product Description

The JASON INDUSTRIAL B66 is a rubber V-belt designed for industrial power transmission applications. Sized at 5/8 inch wide by 69 inches in length, this is a B-section belt built to transfer rotational power between sheaves in a wide range of mechanical drive systems. It is constructed from black rubber, providing resistance to heat, flex fatigue, and wear under continuous operation. HVAC technicians, millwrights, and industrial maintenance professionals install this belt type on equipment including blowers, fans, compressors, and pumps where a standard B-section drive belt is specified.

The B66 is suited for both commercial and light industrial applications. It fits drive systems that call for a B-section V-belt with a 69-inch outside circumference. Common installation scenarios include belt-driven fan assemblies in air handling units, industrial blowers, agricultural equipment, and general machinery. The belt ships in a package quantity of 20 units, making it appropriate for stocking at service shops or facilities with ongoing belt replacement needs.

Key Features

• B-section V-belt profile for standard sheave fitment across industrial drive applications
• 5/8 inch width by 69 inch length for precise drive system sizing
• Black rubber construction resists heat, flex fatigue, and abrasion
• Sold in package quantities of 20 for shop stocking and fleet maintenance programs
• Suitable for blower, fan, compressor, and pump drive applications

Compatibility

Designed as an OEM-style replacement B-section V-belt for industrial and commercial drive systems requiring a 5/8 inch by 69 inch belt specification.

Installation Notes

Belt replacement should be performed by a qualified technician. Always de-energize and lock out the equipment before removing or installing any drive belt. Relieve tension on the drive by adjusting the motor mount or tensioner before removal — never force a belt over a sheave flange. After installation, set belt tension according to the equipment manufacturer's deflection specification and inspect sheave grooves for wear before placing the unit back in service.
