Damper telescope

A special kind of compression gas springs rare ossurrence. It only has a braking function, it does not release force and therefore stops at any position without load.

Size range:

Within the range shown in the table below, we produce damper telescopes, even in individual sizes.
The ends of the gas springs are threaded in principle, but can be chosen from a large variety of end fittings as required.

Type	A	B	C	Possible damperings			D	E
Type	Rod Ø [mm]	Cylinder Ø [mm]	Stroke [mm]	Extension	Compression	Both direction	Basic lenght calculation [mm]	Extended lenght calculation [mm]
FBG06	6	15	20 – 300	X	X	X	(C x2) +35	(C x2) +35 +G +H
FBG08	8	18	25 – 400	X	X	X	(C x2) +45	(C x2) +45 +G +H
FBG10	10	22	30 – 500	X	X	X	(C x2) +50	(C x2) +50 +G +H
FBG10/27	10	27	50 – 700	X	X	X	(C x2) +50	(C x2) +50 +G +H
FBG14	14	28	50 – 800	X	X	X	(C x2) +50	(C x2) +50 +G +H
FBG20	20	40	50 – 800	X	X	–	(C x2) +75	(C x2) +75 +G +H

The value of G and H are different for each fitting type.

Function and structure:

The damper telescope is a cylinder filled with oil, which is divided by the piston rod into two interlocked internal chambers. When pushed by an external force, the oil in the piston openings causes an overpressure to cause the telescope to brake, over the entire lenght of the stroke.

Parts of dampers:
1, end fitting 2, piston rod 3, guiding element 4, seal 5, piston 6, oil 7, cylinder

Application:

Building engineering, furniture , automotive industry and all other places where telescopic power in not needed, but it is important to slow down and brake the structure.
