Abstract: A product with an automatic identification and data capture (AIDC) device associated with a physical measurement, authentication code or operating condition of the product is disclosed. A bearing with an embedded transponder is illustratively described. The transponder contains data specific to the manufactured bearing, such as physical measurements or identification numbers.

Abstract: A seal assembly for closing the end of a bearing includes a seal and a shield on which the seal is captured. The shield has an axially directed mounting portion, an axially directed overhang and a radial end wall between the mounting portion and overhang. The seal has a pumping labyrinth presented toward the mounting portion, yet spaced from it, a dirt lip directed obliquely toward and contacting the mounting portion, and a secondary lip directed obliquely toward, yet normally spaced from, the overhang, with the dirt lip being between the labyrinth and the secondary lip. The labyrinth is exposed toward the interior of the bearing and has pumping cavities which impel lubricant back into the bearing. Between the dirt and secondary lip is a groove which opens toward the radial wall of the shield, and this groove contains a ring of grease-type lubricant which extends to and adheres against the radial wall, thus forming a barrier to the ingress of contaminants.
