Steel Disc Couplings TND, RLDS & RLDM
Our Steel Disc Couplings of the RINGFEDER® TND, RLDS and RLDM series – originating from the proven GERWAH®, TSCHAN® and RATHI® product lines – stand for the highest levels of precision, dynamic performance and availability in modern drive systems. The backlash-free, torsionally rigid couplings transmit torque wear-free via high-quality disc packs made of stainless steel while simultaneously providing reliable compensation of axial, radial and angular shaft misalignments. Thanks to their high torsional stiffness, low restoring forces and excellent running characteristics, they are particularly well suited for applications involving high rotational speeds, precise positioning tasks and increased requirements for process reliability. Whether in machinery and plant engineering, process technology, power generation or complex process plants, the couplings ensure permanently precise and maintenance-free torque transmission. With the modularly designed RINGFEDER® TND series, flexibly configurable standard and customized solutions are available for a wide variety of drive concepts. The RINGFEDER® RLDS and RLDM series complement the portfolio with API-compliant couplings for process and high-speed applications with the highest demands on power density and reliability.
