Hi every one, I need your assistance for calculating the Buckling load for the hydraulic cylinder. The specifications as follows, Working Pressure : 210 bar Testing Pressure : 250 bar Bore Size : 80 mm Rod Size : 65 mm Stroke : 3060 mm Closed Height : 4505 Mounting Type : Rod end bearing Clevis mount Is there any specific formula for buckling load..

http://en.wikipedia.org/wiki/Buckling Apply Euler's equation. Assume rod is pin jointed at each end for most conservative result.

Calculating your load. Not sure if you still need help. Sometimes the best thing to so is talk to professionals like Beiler Hydraulics. I am sure they would be able to give you great advice on this topic. Every time I have a problem or need service they are there. I hope this helps and good luck.
