Technical Support

We recognise that technical support is highly important to customers and we pride ourselves on our reputation for excellent customer service.

Understanding no two applications are the same, our design engineers work closely with customers from concept design, right through to completion. At Camloc Motion Control, we will design a motion control solution to meet specific requirements, whether that’s selecting the most appropriate existing product from our range, or utilising the latest in CAD technology to rapidly provide prototypes for testing.

Construction of a Gas Strut

Gas struts contains several components, each of which is integral for the safe and successful operation of the component.


Rod component

A rod comes as either precision ground, polished carbon or stainless steel and the surface is treated to improve wear and increase corrosion resistance. Generally, the rod will always be longer than the stroke (see Section 2: Terminology) and shorter than the length of the tube.

Carbon steel can be treated in several ways such as chrome-plating, salt-bath nitriding and using a Nitrotec surface layer treatment. For Camloc’s carbon steel rods, we use a layer of Nitrotec surfacing as this has a number of advantages over the former methods. These include:

  • Better wear resistance
  • Lower frictional characteristics
  • Corrosion resistance equivalent to stainless steel
  • The process is environmentally friendly, non-toxic and produces no acidic by-products


Tube component

Each tube is comprised of a high-integrity, powder coated, carbon or stainless steel seamless welded finish; which is suitable for high pressures.

The internal surface finish and tensile strength of the tube are critical for longevity of the device and burst pressure performance.

Guide and Seal Package

Guide and seal package

Manufactured from plastic composite, the guide and seal package provide a bearing surface for the rod and prevents the escape of gas and ingress of contamination.

As well as plastic composite, the guides used can also be manufactured from zinc, brass or other materials with a suitable bearing sleeve incorporated. Rubber is used as standard for seals.

Piston Assembly

Piston assembly

The piston assembly is manufactured from zinc, aluminium or plastic. For factors involving safety and preventing the rod being expelled, the integrity of the piston to rod attachment is critical.

The piston assembly controls the rate of extension and compression.

End Plug

End plug

The end plug is used to seal the tube end, with this also attaching to the tube end fitting. Camloc’s Vari-Lift™ can be incorporated here where required, allowing for the release of nitrogen gas and subsequent reduction in force.

Nitrogen Gas Charge

Location of nitrogen gas

Nitrogen is used as it is inert and non-flammable, therefore not reacting with any of the internal components.
