Stroke 62 mm to 412 mm

Damping either in one or both directions: The hydraulic dampers of the product family HBS are made in a slim gas spring design and are compact and high in performance. Maintenance-free and ready-to-install they allow precise setting of retraction and extension speeds without any free travel when changing direction.

These hydraulic dampers offer constant feeding rates and can be finely tuned via the screw adjustment. A control segment on the piston makes the adjustment at the end position child’s play. Thanks to many add-on components the assembly is easy to mount, so that the damper can be universally deployed for damping back and forth swinging masses, such as in power or free conveyors.

In addition to the automotive sector, the application areas are industrial applications, classic mechanical engineering, the electronics and furniture industry and medical technology.

Technical data

Compression and extension force 30 N to 3,000 N

Stroke 62 mm to 412 mm

Outer body diameter Ø 28 mm

Piston rod diameter Ø 8 mm

Lifetime Approx. 10,000 m

Operating temperature range -20 °C to +80 °C

Adjustment Achieved by turning the piston rod in its fully extended or fully compressed position.
Clockwise rotation = increase of the damping
Anti-clockwise rotation = decrease of the damping
Damping force adjustable before installation. The adjustment can add a max. of 5 mm to the L dimension.

Positive stop External positive stops 1 mm to 1.5 mm before the end of stroke provided by the customer.

Damping medium hydraulic oil

Material Outer body: zinc plated or coated steel; Piston rod: hard chrome plated steel; End fittings: zinc plated steel

Mounting in any position


Increased break-away force if unit has not moved for some time.

End fittings

They are interchangeable and if necessary must be positively secured by the customer to prevent unscrewing.

Safety information

For long strokes with high forces use swivel mounting block MBS.
