ISOFLEX NBU 15 is a very high-quality lubricant made from strictly selected raw materials. KLUBER ISOFLEX NBU 15 has technically surprising features and finds its best use in extremely high speeds. When a bearing is working at high speed, the grease inside tends to spin outwards and in a short time it can leak all the lubricant and then hold on. ISOFLE NBU 15 withstands extreme speeds and is used in the drill chucks of other machine tools. Another special feature of this lubricant is the operating temperatures. Please note that it can also be used in temperature ranges of -40°, although the drip point is +200° at high temperatures.
