Automatic rotary tensioners are automatic devices which allow to keep the right tension of the transmission chain so it lasts longer.

In addition they recover the stretching that the chain has little by little during its functioning.

So thanks to the automatic rotary tensioners you can avoid vibrations and noise linked to functioning.

These automatic rotary tensioners do not need the intervention of any workers so you can save time for the maintenance and for the control of the machineries on which they are set up. 

- Steady belt/chain tension

- Less noise

- Better transmission performance

- Less wear and tear

- Cheaper and easy to set up. 

They are set up and checked manually one by one  by a skilled staff to get the best quality control and perfect functioning.

The high quality materials, the workmanship and the components tolerance made with our CNC machinery allow the product to work perfectly and have a very long life expectancy. The simple functioning and good price make this product an economical, practical and safe one.
