When you look into the sight glass of your cryopump, and notice a black powder residue coating the window, the bearings and other internal parts?
Bad news: Your pump may have been installed with graphite scotch yoke bushings.
Good news: You can now replace those old bushings with a new material developed by DuPont specifically designed for this application. Lightweight, durable, low wear and low friction, bushing material.
Upper and Lower Bushings come with a standard Cryopump Repair Kit for all models.
Or you can purchase the bushings separately.
