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.
