Kit Masters highlights its new PolyForce Belt Tensioner line. Kit Masters says that the new line of products was built in response to common causes of failure in traditional belt tensioners, including spring failure and bearing failure.
PolyForce Belt Tensioners replace the internal spring with a Polymer Torsion Core, which is a molded silicone that lasts longer than a spring. The Polymer Torsion Core also acts as a built-in damping mechanism, which adds to the life of the belt tensioner and adjacent accessories, the company says.
In addition to the Polymer Torsion Core, PolyForce Belt Tensioners feature pulley bearings that can withstand the vibration that tensioner pulleys encounter, according to the company.
Another common cause of failure in belt tensioners is misalignment, which can lead to damaged tensioners, belts and accessories. A worn pivot bushing is typically the culprit of misalignment. PolyForce pivot bushings have a much wider stance, giving them increased stability and long-lasting alignment, Kit Masters says.
PolyForce Belt Tensioners are available as complete units or in a modular system that allows distributors to carry a few individual components from which they can build the required belt tensioner on demand. The belt tensioners come with a two-year, 200,000-mile warranty.
