Experience with hydraulic linear drives

[simon]

Good day,

what experiences do you have with hydraulic linear drives?

I have used a Lecomble and Schmitt for about 7 years and about 20000 miles without big problems. I have changed the carbons once, that is all. The only cosmetical issue is surface corrossion.
I am planning to install a new autopilot and collecting information about the various elements.

What other drives are there, which can be recommended for quality, reliability and servicing?


- Simrad HDL Series
- Raymarine
- Octopus Linear drives ( claim to be more efficient than others????)
- Lecomble and Schmitt
- JGTech http://www.jgtech.com (never heard of them before, seem to be cheaper)
- Or any other drives you can recommend

Thanks in advance.

Simon
