Spidex torsionally flexible shaft couplings, also known as jaw couplings, enable the connection of shafts or flanges via a polyurethane drive ring. The flexibility of the drive ring allows the power transmission coupling to compensate for parallel, angular and axial displacements. Maximum shaft diameters of 145 mm can be accommodated with maximum torques up to 15,000Nm and maximum speeds of 19,000 rpm.
