Why Choose Ringfeder Steel Disc Couplings TND HDH?

Steel disc couplings of the Ringfeder TND HDH type stand out with features such as being completely backlash- and maintenance-free, offering highly effective compensation for angular, axial, and radial shaft misalignment, and providing torsional rigidity with high stiffness.

They also minimize restoring forces during shaft misalignment thanks to an optimized disc pack design, bridge large shaft distances using spacers available in standard or customizable lengths, and meet ATEX standards for fire and explosion prevention.

The TND HDV coupling is widely used in applications such as pumps, fans, compressors, generator and turbine drives, and axial and radial blowers. It is also ideal for paper and printing machines, mixers, stirrers, extruders, lifting and traversing gears, as well as marine and water screw drives.
