Abstract: Methods, systems, and computer readable medium for optimizing physical products. The method includes detecting a set of physical attributes for each physical item among multiple different physical items, obtaining a velocity factor for each of the physical items, generating a mapping of a velocity contribution to various combinations of physical attributes among the set of physical attributes based on the velocity factor for each physical item and the set of physical attributes of that physical item, determining, based on the mapping, that the velocity factor of a particular physical item will increase in response to a change to one or more physical attributes of the particular physical item, and transmitting, to a source of the particular item, an electronic message that conveys the increase to the velocity factor of the particular physical item that will result from a selection of the one or more physical attributes of the particular item.

Abstract: An earth bit includes a cone rotatably mounted to a shaft with a hub unit and thrust roller bearings. The hub unit is moveable between mounted and unmounted positions on the shaft, as a single unit, in a repeatable manner. The hub unit includes a pair of roller bearings positioned between inner and outer races. The outer race includes a recess extending around its outer periphery. A sealing structure is slidingly engaged with the recess to provide a seal between the cone and shaft.

Abstract: Aspects of the present invention overcome one or more of the above mentioned problems by using improved bearing assemblies and/or improved wear ring liners. For example, an aspect of the present invention includes configuring a bearing assembly to include a wear ring having an integral wear ring liner which allows oil or other lubricants to pass along or through the wear ring. In aspects of the invention, the wear ring liner is of a low abrasion, low friction material such as a polymeric (e.g., nylon), synthetic rubber, elastomeric, graphite, and/or other low friction lining material. The low abrasion/friction liner material provides a cushioning between the wear ring and the shaft. Thus, fretting of the shaft is substantially reduced or eliminated while at the same time allowing the wear ring to derive its concentricity directly from the shaft.
