Rotor shafts

Large range of rotor shafts. We reconstruct shafts that are no longer available and manufacture them precisely from high-quality tempered steel.

Shrink discs

The rotor body and shaft are connected by shrink discs. This transmits movements and absorbs axial forces. We have numerous solutions for highly stressed shaft-hub connections.

Pulleys

High-quality pulleys for impact crushers, securely fastened with our shrink discs.
