Stubby Hollow Plunge Cylinders

Hi,

Does anybody know of a "stubby" Hollow Plunge Cylinder. Ideally, I would like somethign akin to a pancake cylinder but with a hole through the middle. To get a rough idea of dimensions, the inner diameter will need to be about 70mm and the length would need to be 150mm max, smaller is better. Travel distance will be <50mm and thrust to be applied is 5kN.

Enerpac seem to be the dominant brand and I can't seem to find another manufacture of this kind of product.

Does anyone have experience with these types of devices?

Thanks
Steve

THE CYLINDER YOU WANT IS NOT IS LIKE THE ENERPAC CYLINDERS BUT WITH 5KN OF FORCE. fOR ME IT IS EASY TO MANUFACTURE BECAUSE WE PRODUCE THIS KIND OF CYLINDERS B.T.O. WITH SMALL COST. MY LOCATION IS IN GREECE SO i DO NOT KNOW IF IT IS EFFORTABLE THE TRANSPORTATION....
TRY TO FIND A WORKSHOP WITH EXPERIENCE. THE PROBLEM IS THE MATERIALS YOU NEED.
THE COST FOR THIS KIND OF CYLINDER SHOULD BE ABOUT 200-250EURO.

Try Bimba. You need around 150 PSI for the 5 kN force.

Does PSI not depend on the surface area of the plunge element?
