Grease - Oil-Air Lubrication


Significant progress and increases in output have been made in the area of grease lubrication for high-speed bearings. However, grease lubrication is still 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 amount of lubricant can be controlled and is released precisely into the bearing, even under high speed. This reduces the number of parts in the bearing and simplifies the overall possible construction of the spindle.
