High quality and long service life: The hydraulic dampers of the product family HB can also be used as single or double acting brake. Its coated body and piston rods with wear-resistant surface treatment 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. The control segment on the piston makes adjustment at the end position child’s play. Thanks to a broad selection of end fittings the assembly is easy to mount, so that the damper can be universally deployed for damping swinging masses, such as in power or free conveyors.

Technical Data

Compression force max. 224.81 lbs

Traction force max. 674.43 lbs

Outer body diameter Ø 1.10 in inch

Piston rod diameter Ø 0.39 in

Lifetime Approx. 250,000 cycles

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

Separator piston Available as a special option without free travel achieved by separator piston and nitrogen accumulator.

Operating temperature range -4 °F to 176 °F

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. Adjustment can add a max. of 0.24 in to the L dimension.

Positive stop External positive stops 0.04" to 0.06" before the end of stroke provided by the customer.

Damping medium Hydraulic oil

Mounting In any position

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.

Application Examples

HB12-70 Regulated operating tempo
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 ...

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 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 compressive ...
HB12-70 Wheel remains in shape with hydraulic dampers
HB12-70 Wheel remains in shape with hydraulic dampers
Incorrectly tensioned spokes can cause the rims of bicycle wheels to distort. To avoid this, consistent values are always required when tensioning. This is assured by ACE hydraulic dampers installed in high-quality wheel aligning machines in the Netherlands, thus ensuring a seamless production process. This is because in contrast to the rubber dampers previously used in the machine, the better ...
HB12-70 Hydraulic dampers: Also good for the environment
HB12-70 Hydraulic dampers: Also good for the environment
The innovative designer of the Wingsprayer from the Netherlands relies on ACE hydraulic dampers to make the spraying of agricultural chemicals more efficient, being gentle on the environment at the same time. They stabilize the delicate wings of the machine so that these can press the plants to be sprayed downwards slightly. The utilization of aerodynamic air currents and the effect of the air ...
