DEFINITION

Classification: 384/445

Antifriction bearing:

(under subclass 91) Subject matter wherein the friction is in the nature of rolling friction, as in a ball or roller bearing.

(1) Note. Bearing assemblies and identifiable elements of bearing are in this and indented subclasses.

(2) Note. A bearing assembly is those elements necessary for the operation of the bearing, that is friction reducing function.

(3) Note. Antifriction bearing subcomponents are classified here if they are disclosed, e.g., whether the bearing subcomponent is for a plain or antifriction bearing, then the bearing subcomponent is classified above under plain bearings.

92+, for an antifriction bearing with conventional roller drill bit structure.

126+, for an antifriction bearing combined with a plain bearing.
