Expansible Shafts Design and Construction and Consulting.
Our pneumatic expanding shafts are obtained from high strength aluminum alloy profiles or in high quality steel.
They are custom built according to your requirements. Our pneumatic shafts are self-centered and have independent air chambers, suitable to blocking cores with an internal diameter of 152.4 mm.
According to customer requirements, these shafts are available with 6 or 9 strips.
They usally have: 3 strips centering and 3 blocking strips.
In our range of products, for cores with an internal diameter of 152.4mm, we can found the 6” pneumatic shafts in a light aluminium version.
The light version includes the same characteristics as the normal version but in this case the shafts will be able to support a lighter weight.
These shafts are built with:
a highly resistant milled and light aluminium alloy shell
An example of a Pneumatic Expanding Shaft with a highly resistant aluminium alloy casing.
This is a 6" pneumatic shaft with 9 strips, 3 blocking strips and 3 centring strips (or vice versa), ensuring the best possible centring.
They have been designed to using also on metalizing machines.
The profile is very strong and it can be support heavy loads; according to the centre distance between the shafts, it can bear up to 4000 Kg.
