DEFINITION

Classification: 384/477

With specified seal:

(under subclass 456) Subject matter including means for preventing matter from entering into, passing through, or escaping from the bearing.

(1) Note. The bearing can be in a support means and the seal acting at the juncture of adjacent elements.

(2) Note. A broadly recited seal, e.g., bearing seal, etc., which recites no structure is classified on the basis of the bearing structure, rather than here.
