To select correct mounting, following<br />

data are needed:<br />

1) Load per mounting (kg)<br />

2) Interfering frequency (Hz)<br />

(Hz = rpm / 60 )<br />

Select correct load line in diagram 1 and<br />

correct interference line in diagram 3.<br />

The load line intersects with required type<br />

of mounting.<br />

Connect this intersection point vertically<br />

down to the interference line in diagram 3.<br />

Here, on the sloping curve, the isolation<br />

degree is indicated.<br />

For static deflection, see diagram 2.<br />
