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 tensioners you can avoid vibrations and noise linked to functioning.

These automatic rotary chain 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. 

Rotary chain tensioners type TCR1 and TCR2 have a light alloy body and lever  and a sprocket. 

They have the body and the lever made of a special anti-seize light alloy perfect for this use. They have a perfect sliding of the lever on the zinc-coated central pivot. They are back closed with a zinc coated hexagon.

The internal steel elastic elements have a very high yield point and initial pre-load. There is a steady pressure excursion.

The lever has a bore in the right position to have room enough to set up any accessories keeping the elastic elements loads  within the mechanical limits. By this way the products has a very long life. 

They include a sprocket with double shielding bearing of various sizes and materials.

The set up is very easy you can use an internal or external screw to fix them to the  machine.

Useful tensioning angle 45°TC2 and 60°TC1 in both sense of rotation.

They can work with a temperature up to 130° C. 

Therefore : 

- 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.
