Double-stroke gas springs
Stabilus IndustryLine double-stroke springs have been developed for heavy flaps with a large opening angle, which are characterized by a low starting and a high ultimate force. These springs have two pressure cylinders that can be filled differently and thus are able to cover two force ranges.
The compression of the piston rod generates a bent characteristic curve, which can be better adjusted to the force progression of the flap.
Double-stroke springs are specially designed for the application you require. The force ranges are exactly attuned to each other and adapted to the required kinematics. Stabilus IndustryLine double-stroke springs are available in steel, AISI 303/304 and AISI 316L/316Ti.
