Automatic belt 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 belt 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. 

The type ETPU has  a light alloy body and tensioning head . They include a pulley. 

The body is made of a special anti-seize light alloy that is perfect for its use. The anti-seize material allows the steel studs to slide perfectly. They are inside and pushed by steel springs. On the studs we set up a aluminum head with a threaded hole with where you can set up our pulleys, plate wheels, sprockets, etc.

The working range can reach 130°C. 

They include pulleys set up on the tensioning head. The pulleys are available in various sizes and materials. 

On demand it is possible to have pulleys not included in our website.

They are set up one by one and checked by skilled staff so that we can have a complete quality control and guarantee the perfect sliding of the studs.
