Value Collection 20543728 V-belt 8V 400 in Neoprene Narrow

Product Description

The VALUE COLLECTION 20543728 is a narrow 8V-section V-belt designed for heavy-duty power transmission applications. With a 400-inch outside length, this belt is built for large-diameter drive systems found in industrial HVAC equipment, compressors, fans, and pumps. Constructed from neoprene rubber, it resists heat, oil, and abrasion under demanding operating conditions. The narrow 8V profile delivers higher power capacity per belt compared to classical V-belt sections, making it a common choice for engineers and technicians specifying multi-belt drive arrangements on commercial and industrial equipment.

This belt is used in commercial and industrial settings where high-torque, high-speed belt drives are required. Typical applications include large air-handling units, centrifugal fans, industrial blowers, compressors, and pump drives. The 8V section is a standard narrow belt designation and is specified on equipment requiring heavy-duty power transmission across long center distances. Installation is handled by HVAC mechanics, millwrights, and industrial maintenance technicians.

Key Features

• 8V narrow section for higher power capacity compared to classical V-belt profiles
• 400-inch outside length suitable for large center-distance drive systems
• Neoprene rubber construction resists heat, oil, and abrasion
• Belt number 8V4000 matches standard industry designation for direct cross-referencing
• Sold individually as a single belt (package quantity of 1)

Compatibility

Designed as a replacement for industrial and commercial drive systems specifying an 8V-section narrow V-belt with a 400-inch outside length. Cross-references to belt number 8V4000 per standard industry designation.

Installation Notes

Belt replacement should be performed by a qualified HVAC mechanic or industrial maintenance technician. Always de-energize and lock out the drive system before removing or installing belts. Use proper belt tension tools to set tension according to the equipment manufacturer's specifications — avoid prying belts onto sheaves with sharp tools. Inspect sheave grooves for wear before installing a new belt to prevent premature failure.
