Variability of Diameter
1. Shafts with very high expansion range
These large clamping ranges cannot be realized by pneumatic shafts. The internal elastic clamping systems would be overstretched. Pneumatic mechanical systems with pistons and starting bevels are used here. Depending on the application, these systems can also be accommodated inside the expansion shaft.
If a base shaft is available, adapters are often the solution of choice. In this way almost all requirements can be solved in different ways. The easiest way is to adapt the expansion of the basic shaft to the new sleeve inner diameter using adapters. This is done purely mechanically.
Pneumatic adapters are operated at 6 bar via a filling valve. They can be adapted to the production requirements in length and design of the clamping elements.
For the standard case 3″ to 6″ we also have a standard solution available.
This standard variant is immediately available from stock.
