Gates DriveAlign Automatic Belt Tensioner Idler Pulley

Gates DriveAlign automatic belt tensioners and idler pulleys are replacement components for serpentine and accessory drive systems. The tensioner keeps the proper belt tension, and the idler pulley guides the belt along its path. Together they help the drive belt run quietly and last longer. They are also sold as belt tensioner assemblies, drive belt tensioner pulleys and drive belt idler pulleys.

Key Features:

• Automatic tension control: Tensioner designs maintain consistent belt tension across operating conditions to reduce slippage and noise.
• Precision-built pulleys: Idler pulleys are made for smooth rotation and accurate belt alignment.
• Durable construction: Sealed bearings and robust housings are designed to resist heat, dirt and moisture.
• OE-style fit and function: Engineered to meet or exceed original equipment performance for dependable service.
• Gates quality: Gates is a leading maker of belts, hoses and drive system components, and DriveAlign parts are designed to work with Gates drive belts.

Worn tensioners and idler pulleys can cause belt squeal, belt wear, vibration and accessory drive failure. Replacing them along with the drive belt helps restore smooth, reliable operation. Select the correct child item by part number for your application.
