DEFINITION

Classification: 29/898.052

Ball making:

(under subclass 898.043) Process including the step of manufacturing the ball component.

(1) Note. The term "ball" is broadly used to refer to a bearing component which includes a spherically shaped bearing portion, but does not refer necessarily to "ball" which in many instances is a truncated ball, i.e., cut off (more or less) at opposite ends thereof.
