DAMPERS
Gas springs apply a controlled force and
dampers control an external force. One or the other will satisfy any lid or door control situation.
Dampers are used primarily where a heavy load or door must be lowered or swung in a controlled motion at a constant speed. For example,
dampers prevent a door from slamming shut or swinging wildly open.
TWO STANDARD TYPES
Two types of standard
dampers are available, depending on the physical position in which they are to be used:
• Compression
dampers provide controlled speed in the compressive direction.
• Extension
dampers provide controlled speed in the extensive direction.
HOW DAMPERS WORK
Guden
dampers are similar in appearance and construction to our Guden Gas Springs, except:
(1) The tube is filled with hydraulic oil instead of non-hazardous nitrogen.
(2) Dampers are force-absorbing instead of force-supplying. The oil inside the
damper must pass through an orifice plate, thus controlling speed.
DAMPERS INSTALLATION/OPERATING TIPS
Compression
dampers operate best in the shaft up position so that the internal piston remains in the oil. The lid or door should be closed before full compression is reached.
Extension
dampers work best in the shaft down position. An extension
damper is an excellent end-of-motion stop with appropriate end
fittings: metal for heavier loads, plastic for lighter loads.
SELECTING THE RIGHT DAMPER
As with Guden Gas Springs, size of load, weight of load, direction of motion and location of mounting points determine the correct size. Guden
dampers are available in rod/tube diameter sizes .24" x .59" and .32" x .87", with stroke lengths from 2" to 7", extended lengths from 7.89" to 19.65" and maximum load capacities from 50 lbs. to 100 lbs.
CUSTOM DAMPERS
We can custom make almost any size
damper to suit your application. Dampers are available on special order with custom damping rates, and also double damped in both compression and extension.

Note: The complete part number consists of the Stock Part Number (above) plus the Orifice Plate Damping Identification (above) and the end
fitting you require (see page 50), i.e., GDC50-D-K. The I*, K and Fat Blade end
fittings are stock.
* Extended length is .24" longer with the "I" end
fitting.
