Hydraulic Dampers
HB-28-350

Linear motion control

Adjustable
Compression force max. 2,000 N
Stroke 350 mm

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 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.

Technical data

Compression force max. 2,000 N

Traction force max. 3,000 N

Outer body diameter Ø 28 mm mm

Piston rod diameter Ø 10 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 80 N; dimension L = 2.35 x stroke + 60 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
Damping force adjustable before installation. Adjustment can add a max. of 6 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: coated steel; Piston rod: steel with wear-resistant coating; End fittings: zinc plated steel

Mounting in any position

Note

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