How to mount a Gas Spring
Important product information:
Must be observed prior to mounting, construction or storage Gas Springs!
1: If TSC gas springs, tension springs or dampers are used in environments where a failure of the product can lead to damage to persons and / or material damage, additional security elements must be applied. When installing/removing TSC gas springs or tension springs, the accident prevention measures have to be always obtained.
2: TSC gas springs are under high pressure, it is absolutely not permitted to open the cylinder. TSC gas springs are filled with pure Nitrogen. Nitrogen is an inert gas does not burn, can not explode and is not toxic.
3: Installation + storage of the products:
– Gas springs must be stored with the piston rod pointing downwards
– Tension springs with the piston rod pointing upwards
– Dampers with the piston rod downwards.
Pressure losses as a result of storage according to the instructions are not to be expected; however, the gas springs should not be stored for longer than 1 year.
Prior to installing the products, the film tubing must be removed.
When using the products for the first time (compression/extension of the piston rod) after longer periods of non-use, it is possible that a sticking effect occurs; therefore, stronger forces are required to compress or extend the piston rod for the first time.
4: TSC gas springs are maintenance free, self-care products, the piston rod don’t have to be lubricated, oiled Ed.
5. TSC gas springs, tension springs and dampers are no safety parts!
TSC gas springs are subject to wear and have a limited lifespan, and must depend on the load and the application to be replaced. They must also be protected against corrosion for the life and fatigue strength.
Leakage of small amounts of hydraulic oil may occur; this oil should not come into contact with food or groundwater.
6: Make sure there is sufficient play in the gas spring joints, i.e. avoid rigid installation. If required, Lubrication of the joints reduces wear and extends the life time.
7: Screwed-on fittings (eye, fork etc.) must be screwed in completely and rest firmly on the face if required. Any loose connections must be completely screwed on before instalation. At vibrations the fittings should be secured against loosening by gluing.
8: Make sure the piston rod does not get jammed (for long strokes / products, an additional bearing / guide must be provided); sagging, bending or kinking must be avoided. The cylinder must not be damaged or deformed; Damage to the surface of the cylinder may lead to leak or no longer functions of the spring.
9: If gas springs are heavenly damaged by external influences (deformed, bent, broken, etc.) they must first be depressurized before removing our operating
10: TSC gas springs must not be overheated or be thrown into the fire.
11: Only axial load on gas springs are allowed. Cross or torsion forces must not occur. If necessary, one must choose other connections
12: TSC gas springs must not be stressed on extension, tension springs not on compression.
13: TSC gas springs, tension springs as well as dampers may be used as end brackets if the nominal force 30% is not exceeded (no overstretching or jarring of the product), i.e. the products may only be loaded with their nominal force +30% on compression or tension.
Mechanical brackets should particularly be applied in addition in case of strong forces in order to rule out a jarring or overstretching of the product.
14: Gas springs are made for use at a Temperature range of -20°C to +80°C. Nominal temperatures 20°C, we kindly ask you to specify significant deviations on this at your request.
In case of temperature variations, the compression or tension forces of the products also change.
The viscosity of the oil also changes if temperatures vary.
15: Small damage, corrosion or paint residues on the piston rod lead to a failure of the spring. The cylinder tube must not be damaged or deformed. Generally, all changes on the product made by third parties result in an exclusion of warranty.
16: Tension springs are open systems, i.e. it must be avoided that dirt or other media get into the tension springs through the ventilation hole at the cylinder end. During installation, it is necessary to make sure that the tension springs are not installed in closed systems and ventilation hole always stays ventilated.
17: Locking TSC gas springs have a tube as the piston rod, which contains a release pin. It is necessary to avoid that foreign media such as dirt or cleaning agents get into the piston rod hole. This can lead to corrosion in the piston rod and cause the release pin to get wedged. Preferentially, the locking TSC gas springs should be installed with the piston rod pointing downwards. If locking TSC gas springs are used in environments where they get into contact with cleaning agents (hospital beds), this generally must be specified.
18: Warranty is excluded for any installation suggestions/drawings for TSC gas springs, tension springs and dampers. It must be considered that not all installation parameters can be included in the theoretical suggestion; therefore, the installation must be carried out with utmost care in practice, since friction values or accelerations cannot or can only roughly be considered in the theoretical suggestion.
19: The installation or use of TSC gas springs or tension springs should generally be tested by the user under operating conditions, since the operating or installation conditions are very varied and thus not all parameters can be simulated or tested It is generally necessary to specify whether the products are used under normal conditions (20°C, natural environment = air) or whether foreign media (e.g. water vapour > 80°C, diverse chemicals, cleaning agents) impact on them.
20: Maximum pressure = 160 bars (20°C)
21: Maximum stroke speed = 300 mm/s in installed state.
High stroke speeds or stroke frequencies lead to an overheating and thus to damage to the sealing and the failure of the product. High stroke speeds or accelerations must not lead to an overload of the product.
22: Length tolerance of the products = +/- 2 mm
23: The tolerance for compression or tension forces generally is:
Maximum +/- 10% of the nominal force (20°C).
The nominal force is measured statically at extending stroke (for tension springs, at compressing stroke) 5 mm before stroke end (standard).
Release force for pushing in the release pin for locking TSC gas springs: approx. 18% of the nominal force F1 of the gas spring.
24: Life time: Depending on the function, the series and the stroke of the gas spring, a life time of more than 50,000 load changes is possible. Environmental influences and the installation situation can significantly reduce the life time.
25: All TSC gas springs are marked with the safety warning “Do not open – high pressure”, the product number and manufacturing date. Any attempt to illegible this data by removing the label, repaint our any other way will lead to excluding of warranty.
26: Disposal: Dampers, TSC gas springs and tension springs are under pressure. They must not be opened or heated up. The products may only be opened according to the instructions.
All products have an oil filling; this must be disposed of according to the Waste Management Law.
Warranty is excluded for any non-observance of the above instructions.
