Heavy-Duty Fan Belt Tensioner, Spring-Loaded Assembly SKU: QT58786

This tensioner is a robust, spring-loaded unit designed to maintain correct belt tension in cooling fan drive systems, reducing belt slip and preserving smooth operation under load.

Built with precision bearings and a sealed pulley, it resists contamination and ensures long-lasting alignment even in dusty, high-vibration environments.

• Spring-loaded arm delivers consistent tension across varying belt stretches
• Sealed bearing pulley keeps out dust, moisture, and debris
• High-strength housing resists deformation under vibration and side loads
• Rigid alignment ensures optimal belt tracking and reduces wear
• Pre-lubricated components provide maintenance-free performance

Installation Tip: Remove the old tensioner by relieving belt tension, mount this unit so its pulley aligns perfectly with the belt path, tighten the mounting bolts evenly, and rotate the belt by hand to ensure smooth motion before operation.

This tensioner is engineered as a dependable replacement to maintain consistent drive belt performance in demanding field conditions.
