ZETASASSI® AUTOMATIC LINEAR DRIVE TENSIONERS - ET
Automatic linear 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 linear tensioners you can avoid vibrations and noise linked to functioning.
These automatic linear 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 linear tensioners type ET has a light alloy body and tensioning head .
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 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” .
For all the sizes there is also a type without the head for special applications such as the cushioning ETBASE.
