BICYCLE BEARING SYSTEM
A bicycle bearing system comprising: an integrated cup, the integrated cup having an outer diameter; a plurality of rolling elements configured to abut and rotate against a first race groove located on an inner surface of the integrated cup; a second race groove configured to abut and rotate about the plurality of rolling elements, the second race groove located on an inner surface of the inner race, the inner race having an inner diameter; where the rolling elements do not have a separate outer race, but rather the inner surface of the integrated cup acts as the outer race to the rolling elements; and where the rolling elements, integrated cup and inner race are axially locked when assembled as a single cartridge unit due to the geometry of the rolling elements, first race groove and second race groove.
Arcuate electrically conductive assembly for bearings
An electrically conductive assembly prevents current flow through the raceways of a bearing disposed about a shaft and an outer ring disposed and within a bore of an outer member. An arcuate conductor has a centerline, an inner radial end engageable with the shaft or a bearing inner ring, an outer radial end and two circumferential ends spaced circumferentially apart such that an arcuate gap is defined between the two ends when the conductor is installed about the shaft or the bearing inner ring. The two circumferential ends define a gap angle about the centerline, the gap angle having a value of at least thirty degrees. At least one conductive coupler is configured to attach the conductor to the outer member, another member or the bearing outer ring such that an electrically conductive path extends through the conductor and the at least one coupler.
