Gates automatic belt tensioners are application-specific and OE-equivalent or better in both performance and fit.
 
To reduce belt warranty problems, comebacks and labor claims, Gates engineers recommend that the serpentine belt and its automatic tensioner be replaced at the same time. It is highly probable that the source of belt damage (tension loss, excessive vibration, misalignment, etc.) is the result of a worn tensioner.
 
Gates DriveAlign™ Auto Tensioners

Gates tensioners ensure proper performance on serpentine belt drives and reduce noise and vibration levels.
Gates asymmetrically dampening tensioners provide more energy absorbsion versus conventional symmetric damped tensioners.
Gates tensioners helps to prolongs life of other accessory drive components.
 
Gates Idler Pulleys
Gates has a complete line of idler/tensioner pulleys for V-ribbed and V-shaped belt drives.

Made of steel and thermoplastic, Gates DriveAlign™ idler/tensioner pulleys provide excellent wear resistance, heat dissipation and dampening.  They resist dust, grit, salt, and other contaminants that reduce pulley life.  The extra long life bearings are designed to operate under high temperatures and exhibit less wobble.  Gates idler pulleys also reduce wear, vibration and friction on belts, thereby extending belt service life.
 
Made of premium materials for longer wear life and higher load capacity.
Designed to operate under severe conditi*** and provide greater reliability.
Built with premium bearings and seals that can operate at higher temperatures.
