摘要： A slew bearing system includes a first bearing ring and a second bearing ring concentrically positioned relative to each other forming at least upper and lower raceways there between, a plurality of bearing rollers positioned in each raceway between the first bearing ring and the second bearing ring, a plurality of delivery nozzles capable of delivering an air and oil mixture into the raceways adjacent the upper raceway, passages capable of fluidly communicating the air and oil mixture through the raceways and collecting some oil from the mixture adjacent the lower raceway, seals capable of regulating air flow through the passages and inhibiting outflow of oil from the raceways, and at least one exit port capable of outward flow of air and oil from the raceways adjacent the lower raceway.
