Chiaravalli produces all its automatic tensioners in Italy. Our automatic tensioners keep the tension of the chains and the belts constant. Their automatic tension action improves the performances and increases the duration of the chains and the belts, thus reducing the maintenance on them. Furthermore, the tensioners can also be used as pressers, to keep any item in the desired position in movement on the transport band lines.
The tensioners are available in a wide variety of models and sizes, they are used in several applications such as agricultural machines, conveyors bands, packaging, bottling and printing machines and industrial applications, where chains or belts are involved.
The high quality of the used materials and the accuracy of the items machining process, make our tensioners, higher quality products, with long-life, capable to withstand heavy loads in any environment. All tensioners with aluminum body/base are black painted through the cataphoresis process.
This process consist of the immersion of the parts with a continue electric current. The deposited film confers to the tensioners aesthetic and anticorrosive characteristics, then prolonging ther life time. The tensioners can be provided as single elements, in linear versions AS and L and rotating T and E, or complete of chain tensioner sprockets, belt tensioner roller or chain tensioner sliding block (in polyethylene UHMW high molecular mass 1.000.000 black).
