Abstract
A bearing assembly can be used in liquid service applications where the bearing assembly is intermittently or continuously exposed to liquid, such as below the liquid level of a solid-liquid extractor. In some examples, the bearing assembly includes an annular sleeve and an annular bearing. The annular sleeve is designed to be installed over the end of a rotatable shaft and positioned inside of a housing through which the rotatable shaft at least partially protrudes. The annular sleeve has an outer surface and length parallel to the rotational axis of the rotatable shaft. The outer surface of the annular sleeve may taper radially inwardly along at least a portion of the length of the sleeve. As a result, the bearing assembly and rotatable shaft positioned therein may pivot within housing about the taper of the annular sleeve.
