That sounds like enough filtering to me. The guy in my lab with the homemade air bearing used very little filtering. Of course, he would spend a week making a bearing and then run it for a day before it locked up, don't know if that was an issue of him not having enough filtering or the fact that he was load testing it. I don't know that you could consider his bearing high performance, but it ran fairly fast. Too bad he didn't publish his thesis online. |
