Mount With Dt 406 [ 2026 ]

Mounting the hardware is only half the integration; the control topology must support the DT 406's motion profile.

The term DT 406 typically describes a cone-type rubber-metal vibration isolator (also known as a buffer or silent block). The "DT" often stands for Dämpfungstechnik (German for damping technology) or Doppeltonne (double barrel shape), while the number denotes the size and load rating within a manufacturer’s series (e.g., from Trelleborg, GMT Rubber, or similar European isolation specialists).

A DT 406 mount is characterized by:

Engineers select DT 406 mounts to achieve an isolation efficiency (η) of at least 80% at the disturbing frequency. The formula is: mount with dt 406

[ \eta = 1 - \frac1(f/f_n)^2 - 1 ]

Where ( f ) = machine running frequency (Hz) and ( f_n ) = natural frequency of the mounted system. For DT 406, with static deflection ( d_s ) in meters:

[ f_n = \frac12\pi \sqrt\fracgd_s ]

For a 150 kg load on a DT 406 with ( d_s = 0.005 ) m (5 mm), ( f_n \approx 7 ) Hz. If the machine runs at 30 Hz (1800 RPM), isolation exceeds 90%.

This calculation is why mounting with DT 406 is not arbitrary—it is a tuned solution.

Large fans (impeller diameters 500–1200 mm) often rest on four to six DT 406 buffers to prevent structure-borne noise from traveling into ducts and building steel. Mounting the hardware is only half the integration;

The ADM Delta uses a patented "DT" locking lever that mimics the 406 interface without needing tools.
