Assembly and use of gas springs

Once gas springs are ordered and/or filled for you, they cannot be exchanged or returned.

Usage:

Mounting gas spring – The gas springs are designed for use within a temperature range of -30 to +80 degrees Celsius.

The extension force F1 is measured at +20 degrees Celsius. There is a deviation of +/- 3-4% pressure increase/decrease per 10 degrees Celsius. Refer to our explanatory page for tolerances on extension force and length dimensions.

Gas springs must operate absolutely free from lateral forces, shocks, and vibrations. The piston rods must also be kept free from damage and dirt.

A gas spring is not a safety product, meaning if gas springs are used in places where failure of the gas spring could pose danger and risk to persons and/or the environment, additional safeguards must be implemented.

A gas spring should not be used as an end stop. Gas springs may be loaded with an additional force of up to 25% on top of the maximum extension or compression force of the gas spring type.

The seals in gas springs are not suitable for installations where the piston rod undergoes a rotating motion.

Gas springs may only be used in the aerospace industry with written permission from T.Technics.

Gas springs should never be cleaned (directly) with a steam cleaner or high-pressure washer. Aggressive cleaning agents are not allowed.

The venting gas in gas traction springs must at all times remain free and unobstructed.

The piston rods should preferably be installed pointing downwards. Seek our advice for any deviating installations. When using eyes, maintain an axial play of 0.3 to 0.5 mm and a lateral play of 0.5 to 1.0 mm.

With continuous use, a pressure loss of 15% may occur after an average of 30,000 cycles (calculated from a maximum of 500 mm). The number of full cycles may not exceed 5 cycles (calculated from a maximum of 500 mm) per minute at a maximum extension/retraction speed of 300 mm per second.

Changes:

We reserve the right to make changes in material types/choices.

Inventory management:

At normal ambient temperatures, filled gas springs may be stored horizontally for a maximum of 3 months. For longer durations, the gas springs must be stored with the piston rod pointing downwards.

Warranty period:

This is 1 year or 30,000 cycles (whichever comes first) after the delivery date and/or production/reference number marked on the gas spring. These data must not be removed and must remain legible, under penalty of losing warranty coverage. Any modifications not made by us to the gas spring will void the warranty.

Environmental protection:

The gas used in gas springs, nitrogen, is a natural component of our ambient air. Any pressure loss is therefore completely harmless. The other components of the gas springs, except for the oil used, are predominantly made of steel, which can be recycled in the normal manner. The oil must be disposed of in accordance with normal legal regulations.

Scrapping:

Gas springs are filled with a pressure between 10 and 250 bar and must be vented before scrapping. Seek our advice for the correct method of mounting the gas spring.
