ISOFLEX NBU 15
is a high-speed grease with a good pressure absorption capacity.
It consists of a combination of ester oil, synthetic hydrocarbon oil and mineral oil and a barium complex soap. It offers good protection against wear and corrosion and is resistant to water, media and oxidation.
ISOFLEX NBU 15 is primarily used for spindle bearings and highspeed plain bearings, e.g. in machine tools and textile machines. Further applications are in threaded spindles, ball screws operating under high loads, running gear bearings, as a long-term grease in cableway bearings and in precision engineering. It may also be used for the lubrication of tooth flanks in precision gears (e.g. bevel gears in milling machines, electromechanical valve actuators).
Benefits for your application
Viscosity: Kinematic viscosity of the base oil, DIN EN ISO 3104 / DIN 51562-1 / ASTM D445 / ASTM D7042, 100°C approx. 4.5 mm²/s
Service Temperature -40° Celsius to 130° Celsius
Tried and tested over many years especially in high-speed applications
Longer component life due to optimized wear protection and good pressure absorption capacity
Excellent resistance to water and media as well as above-average anticorrosive additives protect bearings against premature failure, thus helping to minimize repair costs
Uninterrupted machine operation due to good pumpability and metering in customary centralized lubricating systems
Low intrinsic bearing heat due to low lubricant friction enabling longer service life
