Miniature gas spring manages precision engineering and heavy lifting

Lesjofors - European Springs & Pressings : 07 November, 2012  (New Product)
Lesjöfors has developed a new gas spring with a cylinder of just 12mm diameter and a rod diameter of only 4mm. It is now available as a standard part in over 110 different combinations of lengths and forces. The driving force behind the development was a customised solution for a customer in Belgium. It will be an excellent alternative for applications needing low force demands in limited space in the applications.
Miniature gas spring manages precision engineering and heavy lifting

Lesjöfors has developed a new gas spring with a cylinder of just 12mm diameter and a rod diameter of only 4mm. It is now available as a standard part in over 110 different combinations of lengths and forces.

Lesjöfors’ representative in Belgium and Luxemburg, NV Inexal, developed a small gas spring for a brand new project, where low force, smooth damping and space saving were essential. The Lesjöfors gas spring design department in Stockholm was contacted immediately. They confirmed that a new product size with diameter 12mm was already on the drawing board.

An intense period with fine-tuning of interior component design and sample making was initiated. The development process was coordinated from Stockholm and went on in close cooperation with both the customer and the Lesjöfors manufacturing team. In August 2011 the tailored gas spring had technical approval, and the first order comprising 60 000 pieces was placed.

Erik-De-Preter and the new 12-4 spring from Lesjofors“Both the customer and I were impressed by the speed of the new gas spring product creation, including the sample service and the ability to adapt to the requirements of the application. It was also impressive the pace with which Lesjöfors built up a completely new line for mass production”, says Erik De Preter, the sales manager of Inexal, Lesjofour's representative in Belgium and Luxembourg. He now sees yearly demand of the gas spring taking off to more than 100,000 units.

This led to a plan to launch this variant as a standard product in the new 12-4 size. It will be an excellent alternative for low force demands and limited space in the applications, and a welcome complement to the already wide standard gas spring offer.

The forces of the 12-4 gas spring range from 10N up to 140N. The smallest forces offers stylish lift assist in precision engineering applications, while the gas springs with over 100N are powerful enough to be alone or in couples coping with really heavy items, in very limited installation space.

Various end fittings, such as forks, loops and ball cups, are available from stock. All gas springs and end pieces will shortly be made available for download in 3D CAD via the company website.

As with other gas spring sizes, customised solutions are available for the 12-4 range, including length and strength, colour or logo on the cylinder, customised cushioning, or attachments.
