Berthold Marx is proud to have served industry since 1945

Since the beginning of the 1970s we have been developing both our knowledge in the gas spring market and a product quality on which our reputation is based.Berthold Marx, whose head office is based in Strasbourg (67), continues to invest in its produc-tion facilities, and has established a new unit at Sain Vit (25).

Our strengths:

• Availability • Quick delivery

• Quality

• Service

With more than 1000 gas spring models in stock and a technical sales team at your disposal, we are ready to respond to the specific needs of your industry.

3 BROCHURE GAS SPRINGS

Why use gas springs

When are gas springs needed?To manoeuvre, raise, lower, pivot or counterbalance a load with a precise movement between

two set points at a controlled speed.

There is a wide range of possible applications: All types of industry are exposed to the "Gas Spring Revolution". Car manufacturers were the first users of them in the 1970s. Since then, all car hatchbacks are equipped with gas springs. Industrial engineers have developed many applications for them.

Gas springs are used on nearly all commercial vehicles (mobile sales vans, coaches, lorries, caravans...) hand luggage storage on planes, and also for garage doors, shop display cases (bakeries and butchers etc.) conservatory windows or vents, sunbeds, hospital beds, furniture for office equipment (computers, drafting tables, adjustable chairs.... even sporting equipment etc.)

The range is endless.

The advantages of gas springsOver a mechanical spring:

A gas spring has a hydraulic damping length at the end of the stroke.

A gas spring is more compact than its mechanical equivalent.A gas spring may reach a 10 year life span in certain applications and still remain completely

reliable.A gas spring is corrosion-proof.A gas spring is easy to use.

Choose wisely with BM® Gas Springs!

Definitions and recommendations for use of BM® Gas Springs

Important information Please read carefully.

A Gas spring is not a security device.

1 - DIMENSION AND PRESSURE UNITSAll dimensions are shown in millimetres (mm), all pressures/forces in Newtons (N / F1), and all temperatures are in degrees Celsius (C°).

2 - INSTALLATION CONDITIONS The devices MUST be mounted with the rod facing downwards (with a minimum incline of 15°): For horizontal installation or with rod facing upwards, please contact us. • The springs must not be under any lateral pressure. • Warning: for devices with a welded eyes, allow a margin on the axis of 0.3 to 0.5mm, and

a margin on each side of the eyes of between 0.5 and 1mm. • In the event of particle release, be sure to protect the rod. • If possible, avoid using the device at the maximum calibration.

• If the device is to be painted, protect the rod completely. Do not use solvents to clean the rod.

• The attachment points should be in line. There should be some margin allowed so that the rod is not put under lateral pressure.

• Avoid all impacts on the gas spring. • Never take a gas spring apart: pressurised gas. • Do not allow any paint to get on the piston / rod as this may cause a gas leak.

3 - INSTALLATION WARNINGS Protect the rods against impacts, electric arc flashes, grinding sparks, paint and corrosive prod-ucts. Do not tighten the rods with pliers or in a clamp without using protective lead, aluminium or copper grips.

4 - CONDITIONS OF USE Number of returns/minute: maximum 5. For a higher rate, please contact us. • Endurance level: 30,000 cycles. Loss of durability after cycles: maximum 15% ( the endurance

level varies according to the stroke length and calibration). • Working temperature: from -30° C to + 80° C (at maximum stroke).• Recommended working temperature: + 20° C Output force variation due to temperature: 1% per

3° C.

5 BROCHURE GAS SPRINGS

5 - STORAGE CONDITIONS BEFORE USE • For a maximum duration of three months, the devices may be stored horizontally, in an

ambient temperature. • For a longer storage time, or in a hot country, store them vertically, with the rod facing

down.

6 - GUARANTEE• 1 year starting from the date marked on the device. Example of date marking: 1011 (10th

week of 2011).• For the guarantee to remain in force, if the device is to be repainted the manufacturing date

must remain visible.

7 - NEUTRALIZATIONGas springs hold a pressure of between 20 and 250 bar, and so it is necessary to release the gas before disposal. For your safety, please adhere to the following procedure: • Grip the tube lightly in a clamp. • Split the tube at right angles to the axis in an area of between 30 and 35 mm from the base

of the tube.

To carry this out: • It is ESSENTIAL to wear safety glasses. • Use a metal handsaw.

• Place a cloth over the blade. • As soon as a whistling sound is heard, stop sawing. • The gas removal will be complete when the rod can easily be moved by hand.

8 - TOLERANCE MARGINS

Force in Newtons Margin of tolerance

50 < N < 250 + or – 20 N

250 < N < 750 + or – 30 N

750 < N + or – 40 N

Mechanism diagram

• Forces "F1" and "F3" are measured at distance "C" from the ends of the stroke.• The difference between the spring force and the force required to compress the spring is due

to internal friction "FR".• The SPRING STIFFNESS X = F2 / F1

7 BROCHURE GAS SPRINGS

Choice guide

N = number of gas springs, RH = Meter, m = KG, x2=MeterSpring Force Calculation: F1 (N) = 9.81 x ( (RH x m) / (2 x N x (x2))) + 5 )

Warning - we suggest rounding up to the next tolerance (see page 5)

Other suggestion:

The spring stroke is directly associated with the opening angle of the hatchback, and so we recommend the following ratio:

Stroke = 1/3 of RH per 90°

The installations noted above are examples only and do not in any way incur the liability of Berthold Marx.

LOCKING ON REQUEST

BM® locking Gas Springs are lockable along the complete stroke. Whatever the application (hospital beds, stretchers, standers etc) you can lock and release the spring as you wish. The possibilities are endless with the various models offered in the range: Elastic lockable, Rigid lockable and Absolute rigid locka-

bles.

By opening the valve control integrated in the gas spring rod you are opening the piston valve which allows the fluid to flow: nitrogen in the case of elastic lockable springs and oil for rigid lockables. When you release the control the spring locks in position.

BM® Gas springs can be manufactured in steel,

303/304 stainless steel or 316L/316Ti stainless steel.
