Hi,
I am looking for a compact rotary hydraulic actuator. The smallest that I've found so far is of the helical type and it is manufactured by Helac. This one has a length of 5.5 in.

Are there any that are smaller than this? I would think that hydraulic vane-type rotary actuators can be made smaller, but I wasn't able to find hydraulic vane rotary actuators anywhere. Does anyone know of a manufacturer of hydraulic vane rotary actuators? I checked the fluid power manufacturers directory, but I was still unable to find hydraulic vane rotary actuators.

Thanks!

I need the same element as weel. I'm looking for the smallest possible hydraulic vane rotary actuator if any one knows

Look in the "Designers Guide" onn the Home Page of this Forum to see links to all the manufacturers of rotary actuators.

There is a company called Flow Torq i believe is how they spell it but they make a variety of actuators

I wasn't able to find this company's website. Do you by any chance know their URL?

Never mind, I was able to find it: www.flo-tork.com. They only seem to only have rack-and-pinion hydraulic actuators. Since I'm looking for compactness, I'm looking for either vane or helical hydraulic actuators.

Thanks,

Here is a index of companies making Rotary actuators

What torque value are you looking for at what oil pressure? And what is the application? I might be able to help.
