Radial damper for sliding door
RD 240/241
Dictator Technik
Although designed for sliding doors, they are also used on a variety of other
aplications (e.g. roller conveyors, chain hoists).
RD 240000 and RD 241014 radial dampers dampen by means of a revolving chain
which runs around the toothed wheel (at least one quarter of the wheel should be in constant contact with the chain).
The diagram below shows the default damping direction of the wheel. The direction of damping depends on the direction the chain is run around the wheel. (Please see diagram above). If necessary, you can change the damping direction by removing the lock washer, taking off the wheel and replacing it on the axle the other way round. Make sure you put the lock washer on again.
By the adjustment screw you can adjust the damping force continuously. An internal thermostatic valve ensures that the closing speed remains the same under changing temperatures (-15° to +70 °C).
