HAHN Gasfedern oil damper, damping force 5–2500 N, compression, tension or both directions

HAHN Gasfedern oil dampers are sealed, maintenance-free hydraulic elements. They do not replace a gas spring but limit speed: a lid, carriage or pneumatic actuator rod does not accelerate beyond a set value. Damping is possible on extension, retraction or in both directions, with damping forces from 5 to 2500 N.

The HB series allows the force to be changed by turning the rod if the exact value is not known in advance. All series are available as fixed dampers in steel, V2A (AISI 304) and V4A (AISI 316). End fittings: eye, fork, ball sockets, angle and axial joints. Brackets: support shoe, side, angle and round brackets.

Key features:

• Keeps flap and feed speed within set limits
• Damping in one or both directions
• HB series adjustable on site by turning the rod
• Stainless steel for medical, food and marine use
• Used together with a gas spring or pneumatic actuator

Specifications:

• Damping force: 5–2500 N
