More and more branches of industry are using precision machine tools with high-speed spindles. Speed factors of 2 million or more are possible with these spindles.
For such spindles, oil-air lubrication is often preferred to enable reliable lubrication even at extremely high speeds. It is especially for the stringent requirements in this field of application that Klüber Lubrication has developed a new series of synthetic spindle oils. The PAO-based oils of the Klübersynth FB series have purity class 15/13/10 and are available in the viscosities ISO VG 32, 46 and 68.
The performance capacity of Klübersynth FB 4-68 was tested and confirmed up to a very high speed factor of 2.52 x 106 mm/min for suitable high-speed bearings by Werkzeugmaschinenlabor WZL at RWTH Aachen (Germany).
For OEMs or operators of machine tools who look not only for maximum performance at extremely high speeds, but also for oils of high purity, Klübersynth FB is the right choice.
