About us



High Italian quality power transmission parts.

                                   A constantly evolving workshop without any stop. 


The founder is Mr Sassi Giuseppe who was born in 1947. Thanks to his mechanical skills he was able to use them on traditional or updated machineries such as CNC ones.

After his customers demands and thanks also to his mechanical needs he started to think about a tensioning solution for chains or belts.

So he started trying the spring ones and after many years of tests he had the first tensioner the type TO that nowadays is the most popular and bed imitated.

Over time he made various type of TO even if he keeps thinking to a different product.

And so the idea derived from a conversation with his friend. He thought about the car or truck clutch . So he made the most famous of our tensioners the type TC that until today is the most imitated...
