HB-70

Linear motion control

Adjustable
Compression and extension force 2,000 N to 50,000 N
Stroke 111 mm to 811 mm

High quality and long service life: The HB model of hydraulic damper can also be used as single or double acting brake. Its coated body in a slim gas spring design and the piston rods with wear-resistant surface coating are features of high quality and long service life.
The maintenance free, ready-to-install and closed systems provide a constant feed rate and are adjustable, and the control segment on the piston makes 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.

On automotive or industrial applications, mechanical engineering, medical technology or the electronics and furniture industry, these machine elements are found in a number of different areas.

Technical data

Compression and extension force 2,000 N to 50,000 N

Stroke 111 mm to 811 mm

Outer body diameter Ø 70 mm

Piston rod diameter Ø 30 mm

Lifetime Approx. 10,000 m

Free travel Construction of the damper results in a free travel of approx. 20 % of stroke.

Separator piston Extension force min. 250 N; dimension L + 150 mm. Part number: add suffix -T.

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
The adjustment can add a max. of 5 mm to the L dimension.

Positive stop External positive stops 5 mm to 6 mm before the end of stroke provided by the customer.

Damping medium Hydraulic oil

Material Outer body: Coated steel; Piston rod: Hard chrome plated steel; End fittings: Zinc plated steel

Mounting In any position

Application field Conveyor systems, Transport systems, Furniture industry, Locking systems, Sports equipment

Note

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.

On request

Special oils and other special options. Alternative accessories available on request.

HB12-70 Swinging movements cushioned
HB12-70 Swinging movements cushioned
Passengers always feel the swinging movement involved when cable cars arrive at the ski station. Maintenance-free hydraulic dampers type HB-40-300-EE-X-P cushion these movements perfectly. Designers of the cable cars, connected by means of an articulated joint via a four-point frame and connection guide to the suspension rod, profit from the ability of the adjustable dampers to absorb ...

HB12-70 Regulated operating tempo
In the past, operators of used-clothes containers could sustain injury because the flaps closed relatively quickly and uncontrollably. Various hydraulic dampers of the type HB-15, which are designed specifically for the type of container, regulate the synchronization of the flap in both directions and thereby serve to regulate the operating speed. To accommodate a range of requirements and to ...
