#KMR689408

Sommaire du produit

Les tendeurs de courroie PolyForce de Kit Masters remplacent le ressort traditionnel par un noyau de torsion en polymère plus durable. Ils comportent également des roulements de poulie améliorés pour prolonger considérablement la durée de vie du tendeur de courroie.

Caractéristiques et avantages

No Springs Attached - 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 Core. A compressed silicone replaces the spring, thereby eliminating the primary cause of failure.

Improved Bearings - 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 with Outer Ring Rotation and Anti-Vibration Grease (won’t separate).

No Spring = Less Heat - To demonstrate the difference between tensioners, we ran a PolyForce belt tensioner and a competitor’s belt tensioner along an oblong pulley, which causes it to flex back and forth. After 20 minutes the competitor’s belt tensioner was 62.5% hotter than the PolyForce belt tensioner. Less heat leads directly to longer lasting components and assists in achieving lower under-hood temperatures.
