Hi dear, hope you are doing good.What is the reason of sweating of oil from the rod end gland side of a hydraulic cylinder. I tried every profile and material but this particular cylinder still sweats and leaves a thin layer of oil while going up . That is when we rake the rod completely in and then when it comes out a very thin layer of oul is seen covering the rod unfortunately the customer is not accepting it.

Hi, I see a lot of failures with case drain restrictions on axial piston motors/pumps. Any real-world fixes you have come across that use a spitter valve venting to atmosphere? Sounds like a cheap and easy way to avoid $50k shut downs caused by operator error.

Great site to refresh our learnigs and also get different perspectives.
There is one point that haunts me and it would be great if anyone can address it or at least provide some insight.
I have been trying to precisely understand what is the role of the value of the pressure drop across the main control valve in pre and post compensated systems? i mean what should be the value of the deltaP across the MCV when tested alone? is it simply irrelevant because the deltaP across the MCV is not governed by the compensation spools? or is it still relevant and would be a factor while selecting the components. Frankly, i have not been able to arrive at a precise conclusion.

Very insightful and well written blog/website. This is my first time fiddling with a hydraulic system and I found your site by googling the term "rotating assembly bad" I wanted to read some horror stories of what not to do to avoid problems with my tandem pump rebuild. keep up the good work! :D
