DEFINITION

Classification: 277/358

Relatively rotatable radially extending sealing face member (e.g., face, mechanical, etc.):

(under subclass 345) Dynamic seal including at least one of a pair of opposing surface members relatively rotating at the joint or juncture that defines a sealing face and wherein the joint or juncture is at an angle to a rotational axis formed between the relatively movable parts.

SEE OR SEARCH THIS CLASS, SUBCLASS:

306+, for a process of using a relatively rotatable, radially extending, sealing face member (e.g., face, mechanical, etc.).

348+, for diverse and distinct dynamic seals including a close proximity seal (e.g., contactless, fluent, etc.) and a relatively rotatable radially extending sealing face member (e.g., face, mechanical, etc.).

352+, for diverse and distinct dynamic seals having a relatively rotatable, radially extending, sealing face member (e.g., face, mechanical, etc.) and other than a close proximity seal (e.g., contactless, fluent, etc.).
