摘要

The bearing for the shaft (10) of a centrifugal pump comprises a sleeve (12) which fits around the shaft and has two flexible sealing rings (18) at its ends. The space between these is filled with a viscous material (20), preferably lubricating grease, which is optionally mixed with air or another gas.
