Bearing Fit Chart - Shaft and Housing - Pacamor Kubar Bearings

For example, some high-speed instrument bearings travel at speeds approaching 500,000 rpm. Flow meter bearings travel at slower speeds but face a unique set of pressure, corrosion, and environmental challenges. Finally, many miniature bearings are used in pulling and stressing man-made vacuums and the natural vacuum of space.
