// PNEUMATIC EXPANSION SHAFTS

A practical principle

Simply strong

In the A, 403, L, MB and 409 series, we manufacture pneumatic expansion shafts for use in all areas of the paper or plastics processing industries. With high robustness, the expansion shafts are simultaneously characterised by their low dead weight and simple design according to the modular construction principle. This enables simple exchange of shaft journals and quick repairs.
