The radial damper with toothed wheel module 4 (16 teeth) has been designed in particular for sliding gates, that are normally opened and closed by a door drive unit with the help of a rack. For safety reasons a radial damper should be fitted on all ascending gates to control the closing speed over the
complete travel distance in the event of a power failure.
As the radial damper is mainly used in the exterior it has a special protection against rust.

The radial damper is fixed near the drive unit. The toothed wheel has to be in gear with the rack that transmits the power of the drive unit.

The load on the damper M may not exceed 7
Nm:

M [Nm] = G x sinß x 0,032

{G = weight of the gate in N
ß = ascent in degrees}

The closing speed can be varied between 0,08 and 0,2 m/s at the adjustment screw.
