Gates 38730 FleetRunner Heavy-Duty Automatic Belt Drive Tensioner

The Gates 38730 is a heavy-duty automatic belt drive tensioner, also called an accessory drive belt tensioner assembly. It keeps the correct tension on the V-ribbed accessory drive belt and holds belt alignment steady. That supports drive efficiency and belt life.

Key Features:

• Chrome-silicone round torsion spring, which has less flex-fatigue than flat-spring designs
• Patented damping mechanism that adds stability and reduces vibration, which helps extend the life of the belt, the tensioner and other accessory drive components
• Patented design for belt alignment and tension
• Patented labyrinth seal that keeps contaminants out of the internal parts
• Bearing bore inside diameter of 2.17 in. (55 mm)
• Smooth, backside belt contact surface for V-ribbed belts
• Contents listed as tensioner assembly, bracket and mounting bolt

This tensioner is built for heavy-duty service. It is a suitable replacement when an existing tensioner has a worn pulley, makes noise or has lost spring tension.
