AUTOMATIC ROTATING AND ROTARY DRIVE CHAIN TENSIONERS IN RUBBER

Automatic chain tensioners elements 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. 

Type RHR - RHB  have light alloy body and lever and a sprocket. 

 They have two light alloy bases and a lever whose features are the high sturdiness and the light weight.

Inside the bases there are 4 rubber elastomers with high elastic memory. In addition there is a lever with bore and thread where you can set up the sprocket with double shielding. 

The bore is in the perfect position to be able to have room enough to set up the accessories keeping the elastic elements loads within mechanical limits. The product lasts longer.

They are different compared to similar items on the market as they are completely dismantled so in case of wrong set up or machinery troubles linked to overloads or other causes, you have the possibility to have maintenance and if it is necessary you can replace the internal parts very easily and saving money.

They can be easily set up with internal or external screw.

They have a stop slot to block the rotation.

Tension useful angle 30° in both sense of rotation .

They can work with temperature from - 40° C up to + 80° C. 

Therefore :

- Steady tension of the belt/chain

- Noises reduction.

- Best transmission performance.

- Less wear and tear.

- More saving and easy 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.
