TND Series of Steel Disc Couplings

Featuring backlash-free torque transmission, the TND Series of Steel Disc Couplings allow for positioning accuracy in machines that involve synchronous operation, frequent starts and stops or reversing operations. Typical drive applications include printing and packaging machines, compressors, pumps, and variable speed drives.

Using in-depth finite element analysis, the TND Series includes two coupling types: High Deflection, which offers excellent shaft misalignment compensation, and High Torque, which incorporates a higher power density.

With their high material quality, compact design, and tight tolerances, the couplings achieve good concentricity, maximum operational reliability, smooth operation, and low vibration levels — even in the presence of fast rotational speeds or irregular rotational forces. They also avoid wear, don’t require cleaning or lubrication, and offer a long service life when properly installed.
