I have a mechanical linear actuator that is a ballscrew mechanism with an oil (Mil-H-5606) filled gearbox.
Can someone be so kind to explain why there is pressure build up in the gearbox?
How can I theoretically determine what the optimum oil fill volume for the gearbox should be? The unit...
Thanks guys for the help. I verified that the profilometer did scratch the face seal of the runner, but I am not sure this is the cause of the leakage, yet.
Thanks Mike,

I am pulling these parts and having them lapped with a requirement of no surface...
