The reliable model for the highest operational safety and great track velocities

A high concentricity for high track velocities with sensitive materials distinguishes the SFA expansion shaft. A selection of different expansion bars makesit possible to use cardboard, plastic or steel sleeves.

Clamping by using spring force guarantees the highest operational safety with permanent power transmission with centric clamping. The expansion bars are expanded by supplying compressed air.

The SFA expansion shaft is based on the CTA expansion shaft in the mechanical model, made of high-tensile steel and can be balanced up to G2.5.
