Can I use your plain bearings in a vacuum?

Yes. As regards the criteria that are normally used to select the ideal material for plain bearing applications, the main consideration with regard to use in a vacuum is the amount of moisture the material absorbs. Why? Most materials absorb moisture in some form and this varies according to the plastic. This moisture can come from liquids or from the air: If moisture is absorbed, for example during storage it can be released again in a vacuum and then detracts from the quality of the vacuum. For such use, therefore, iglidur materials that absorb only very little moisture should preferably be chosen.
