(under subclass 7) Subject matter wherein roller or ball antifriction elements circulate within an endless race track, e.g., raceway, part of the time in a loaded, and part of the
time in an unloaded state.
(1) Note. The track usually has one loaded straightway, the one unloaded straightway which are parallel, and circular endways connecting the straightaways.
(2) Note. A race is the object upon which the raceway is formed. A raceway is a bearing contact surface, that is, the surface upon which the other raceway slides or on which a rolling element, such as a ball or roller, rolls.
