High-speed lubricating grease.
Klüberspeed BF 72-23 is a high-performance special grease with a synthetic base oil and a complex urea thickener. The base oil viscosity and the viscosity-temperature characteristics of the base oil allow Klüberspeed BF 72-23 to be used for a wide range of speeds and temperatures.
