Value Collection 20565071 V-belt Section B B300

Product Description

The VALUE COLLECTION 20565071 is a Section B classic V-belt designed for industrial and commercial power transmission applications. Built from rubber, this belt delivers reliable torque transfer across a wide range of belt-driven equipment. It carries an outside length of 301.4 inches and an internal length of 300.30 inches, corresponding to the standard B300 belt designation. Licensed HVAC technicians, refrigeration mechanics, and industrial maintenance trades commonly install this belt profile on fan assemblies, blower drives, compressor drives, and other rotating equipment where B-section belts are specified.

The B-section V-belt is a widely used standard profile in both residential and commercial mechanical systems. It is suited for single-belt and multi-belt drive configurations on HVAC air handlers, rooftop units, exhaust fans, industrial blowers, and general-purpose machinery. The classic style construction follows traditional V-belt geometry, making it a direct fit wherever a B300-designation belt is called out on equipment nameplates or service manuals.

Key Features

• Section B profile matches standard B-section sheaves and pulleys
• B300 belt designation with 301.4-inch outside length and 300.30-inch internal length
• Classic V-belt style construction for broad equipment compatibility
• Rubber material construction provides flexibility and resistance to heat cycling
• Single-unit packaging suitable for direct replacement without minimum overstock

Compatibility

Designed as an OEM-style replacement for any belt-driven application specifying a B300 or B-section V-belt with a 301.4-inch outside length.

Installation Notes

B-section V-belt replacement is typically performed by HVAC technicians, refrigeration mechanics, or industrial maintenance personnel. Always de-energize and lock out the equipment before removing belt guards or accessing the drive assembly. Adjust sheave spacing to relieve tension before removing the worn belt, then seat the new belt fully into the sheave grooves before applying tension. Do not use tools to pry the belt over sheave flanges, as this can damage the belt cords and reduce service life.
