Lubricating elements for linear guides in industrial applications

ISOFLEX NBU 15 by Klüber Lubrication was developed for demanding bearing points where high speeds and reliable lubrication are simultaneously required. A typical application area is spindle bearings in machine tools, where low intrinsic heating of the bearing and a stable lubricating film are particularly important.

The low lubricant friction helps to keep heat development in the bearing low. At the same time, ISOFLEX NBU 15 offers good pressure absorption capacity and protects bearings from wear and corrosion. Klüber specifies a speed factor of up to 1,600,000 mm × min⁻¹ for the grease.

The grease is also resistant to water and other media. This is particularly advantageous in machine tools, as bearing points can come into contact with moisture or cooling lubricants depending on their design and operating conditions.
