. Often while deployed, wear on bearing, shaft, and seal assemblies introduces undesirable clearances between contacting … surfaces, which potentially can affect the performance of hydrokinetic devices. In order to investigate wear occurring …. The wear rate data collected after 60 h of clear-water tests on four different types of bearings is presented. In addition …

to wear on bearing surface, a significant amount of wear on the drive shaft was observed. These results reveal that (in … addition to high wear resistant polymer bearings) a surface hardened shaft may increase the longevity of bearing-shaft assembly … devices such as bearings, drive shaft and seals. The wear on critical sliding components introduces unnecessary clearances …
