<p class="MsoNormal"><span style="color:#1F497D"> My first reaction upon reading your post was to try to convince you NOT to put any sort of lubricant into the chamber if you can avoid it by re-aligning or replacing components. If it is a vacuum system,
you will suffer the effects of outgassing if lubricant is introduced and contamination is a concern as well. If you find that you have to use a lubricant, my suggestion would be to lube the slides only with an inert PFPE lubricant that does not react with
other chemicals or provide any dopant, these products usually have a high temperature tolerance but can form toxic compounds if heated over 300 Deg. C. If you need to heat above this temperature, the next step would be the use of silicone grease. I suggest
sparingly lubricating the slides only since chains can run dry if they remain clean.<o:p></o:p></span></p>

<p class="MsoNormal">In one of the equipment the sample stage which moves up and down from loading the sample in deposition chamber is making noise. The sample stage has chains with motor and bearings/sliders to move up and down. I think if I add lubricant
the noise can be reduced. As this system might be baked to high temperature, I want to know what sort of lubricants to you use in the cleanroom for your equipment, I want to make sure the grease wont dry out during baking or atleast I don’t want to add the
lubricant every time I bake.<o:p></o:p></p>
