Clear progress and increases in output have already been made in the area of grease lubrication for high-speed bearings. Even so, grease lubrication is pushed to its limits, which can only be overcome by an oil-lubrication. NSK's oil-air lubrication works as a safe, economic and pollution free lubrication. With a lubricating hole (groove and hole in the outer ring) the lubricant quantity can be controlled and is injected precisely into the bearing, even under high speed. In addition this reduces the number of parts in the bearing and so simplifies the overall possible construction of the spindle.
