Rotating hydraulic cylinder
Rotating hydraulic cylinder
(OP)
I am designing a rotary hydraulic ram where the shaft is supported on either side of the piston with cylindrical roller bearings. The hydraulic force is created by a significant pressure drop between the piston and the housing, which the fluid will leak by and drain back to tank at atmospheric pressure. Shaft will be rotating at 3600 RPM. Anybody have any experience with a crazy idea like this?
thanks.
thanks.

You will find few of them in publicly available products.
There is a reason.
On the other hand, based on the very limited data you've provided, I don't perceive a guaranteed deal-killer in what you've described.

Some other information: Fluid is 68 centistoke oil @ 75 deg. F. System will limit the heat rise to 150 deg. F.
