Conventional belt tensioners use springs to hold their position and tension. However, springs can only flex so many times before they fail. PolyForce™ Belt Tensioners replace this spring with a longer lasting, new and unique polymer Torsion system.
A compressed silicone replaces the spring, thereby eliminating the primary cause of failure.
The other common failure point in a belt tensioner is the bearing. The pulley bearing absorbs a huge amount of vibration and can often fail too soon. PolyForce™ Belt Tensioners have dramatically improved pulley bearings to give them extended life.
Our bearing is designed specifically for pulley applications and features:
– Outer Ring Rotation
– Anti-Vibration Grease (won’t separate)
Find the appropriate replacement for your belt tensioner by using a vehicle’s year, make, model and engine.
The PolyForce™ Belt Tensioner modular system allows you to stock a few components while maintaining maximum market coverage.
