The torsionally soft CENTAFLEX-CO coupling series was built for use in diesel engine driven systems subject to high torsional vibration. Thanks to the robust and fail-safe construction, rubber rollers are installed under precompression and remain preloaded. This unique, precision-engineered coupling was extensively researched and developed using the ROSTA rubber roller principle for unsurpassed performance. Ventilation of the rubber elements allows elements to withstand high-stress and high-temperature conditions. The CENTAFLEX-CO couplings offer reliability, high torsional elasticity, and wear resistance. The CENTAFLEX-CO couplings offer consistent torsional stiffness throughout the torque range, damp torsional vibrations and shock loads, and compensate moderate axial, radial, and angular misalignments.
