Source for very small telescopic hydraulic cylinders?

[amrbekhit]

Hello all,

I am looking for a source of small, telescopic hydraulic cylinders. I'm looking for a cylinder with a retracted length of approximately 20mm and an extended length of approximately 90mm. The diameter of the main cylinder is roughly 15mm. I do not yet know the required working pressure of the cylinder (see this post), but I know that I need to generate at least 10N.

My internet searches so far have only brought up suppliers/manufacturers of larger cylinders.

Any ideas?

It's usually cheaper to amplify a short stroke mechanically, e.g. with a lever, than to get a long stroke from a short cylinder.

See this article and reference at the end to Air and Hydaulic Power Inc. Mini-space telescoping cylinders. Neat jet boat, too.

@Mike: Thanks for the suggestion - I am working on several concept ideas and one of them is using a similar principle to what you have suggested. However, I am currently assessing the feasibility of the hydraulic method.

@Ted: Useful link: I will contact the company. Thanks
