Simple hydraulic cylinder question
Simple hydraulic cylinder question
(OP)
I've got a fundamental hydraulics question that should be easy to answer.
Is a given hydraulic cylinder able to apply more force while extending than while retracting? If so, is there a standard push/pull ratio?

No standard push/pull ratio.

RE: Simple hydraulic cylinder question
- If you have a double rod cyclinder the forces are equal. These are not very common, with the big exception being steering cylinders on off-road machinery.
- The reason there is no standard push/pull ratio is that the rod diameter is generally based on the needed buckling strength. And the buckling strength is based on rod length and force applied to the cylinder. And the force could be externally generated and thus higher than the hydraulic force.
