Semiflex from SCHMIDT-KUPPLUNG is a torsionally-stiff, precise shaft coupling for transmitting torque from one shaft to another, in those cases where shaft alignment can not be guaranteed due to manufacturing tolerances, assembly procedures, wear or operational specifics. All types of shaft misalignment are accommodated via the Semiflex design. The radial shaft misalignment is compensated via pivoting parallel movement. No restoring forces are induced. The angular velocity of the connected shafts remains totally synchronized, regardless of the shaft misalignment. No restoring forces are induced. The Semiflex requires very little axial space. Misalignment capacity is not a function of coupling length.
