INDUSTRIAL CHAIN AND BELT TENSIONERS

AUTOMATIC LINEAR CHAIN TENSIONERS WITH SPROCKETS AND BEARINGS

Automatic 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 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 ETR has a light alloy body and tensioning head and it includes a sprocket. 

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 body there is a light alloy threaded head where it is possible ti set up pulleys, plate wheels, sprockets, etc. 

The working range can reach 130°C. 

They include a double shielding bearing sprocket set up on the tensioning head. They are available with various teeth numbers and for all the type of chain.

On demand you can get sprockets not included in our catalogue. 

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.

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 .

Various sizes and type of tensioning are available so that you have a product suitable to the type of load, shape and customer’s needs. 

For all version is available a KU type with “ self-lubricating sliding bushes”  suitable for particular uses or when it is not possible to reach easily the tensioner.
