Tensioners are devices used to take up any slack and maintain the correct tension of the transmission. They may be automatic or fixed, linear or rotary; in all cases, however, they are adjustable. The automatic mechanisms may consist of springs or rubber elastomers.The purpose of a tensioner, in addition to picking up the slack in the transmission, is to prevent vibrations, noise and possible breakage of the transmissions. The advantages of its use include: absence of maintenance, better transmission performance, less wear of parts and thus longer lasting transmissions.
All this makes the use of tensioners advantageous from the technical as well as cost savings standpoint.
The bases of our tensions may be constructed in a range of materials: plastic, aluminum, aluminum alloys, in some cases completely machined from solid, also in AISI 304L/316L, or to customers’ requests in any type of material.
The compound we use the most in die-casting is a special alloy of aluminum that is extremely sturdy, with antiseize properties. It actually boasts a tensile strength of 440MPa, while most aluminum compounds have tensile strength around 240 MPa; if we consider that the iron most widely and commonly used is FE360, which has a tensile strength of 360MPa, we can say that our alloy is ideal for this type of application, and is decisive above all for the long life of the product in any situation …
All our materials are machined directly in our workshop using numerical control machines.
Tensioners can also be used as pressing units, shock absorbers, stabilizers and regulator/tensioners of rollers for belts, etc.
