VULKARDAN L are designed for rigidly mounted engines and flexibly mounted engines and boast a torque range of 180.0 kNm to 360.0 kNm. The RATO-S coupling is extremely torsionally flexible rubber coupling that is able to sustain angular shaft, axial and radial shaft displacements of the machinery that is connected to it. The range of damping and torsioning factors available offer the possibility to successfully configure the torsional vibration parameters of the drive system.

The latest ACOTEC lineup of products are defined by their improved and outstanding performance in the significant technical data. The design requirements for the successful RATo-S generic design concept has been re optimized and developed in combination with the refined compound, testing technology, and vulcanization to create a superior performing S+ version.
