Joey, What you really need is like what they have on the machinery for Ali doors and windows, they have modified all the machines at my work to have oil feed compressed air in all the ball screws and linear slides. They are just loner slides to what you have.
It stops the ali dust and swarf from getting in and destroying the assemblies.
Flexable line is used, they also made a boot from hosing , directing the air flow oil etc downwards so as not to have any oil drops get onto the product.
The supply pressure is about 30 psi , I am not sure of the total flow, but not very high.
An inline oiler like what is used similar to that used for air tools.
Originally the machines were greased 3 x a day, but the greas would drip down onto the parts and it did not stop the fine stuff from getting through the seals.
