– Easy handling: controlled wear for tooth flank correction
– Transparent, thin lubricant film, contains UV indicator for inspection
– Clean appearance, hence better acceptance by users


Klüberfluid B-F 2 Ultra is a mineral-oil-based running-in and correction lubricant especially developed for immersion, circulation or spray lubrication. It contains special additives and surface-smoothing solid particles enhancing the running-in process, i.e. physical/mechanical material removal on new tooth flanks. In the same way, the tooth flanks of drives already in use for some time can be smoothened (correction lubrication).

Klüberfluid B-F 2 Ultra is a fluid grease that is free of bitumen and raw materials containing solvents, heavy metals or chlorine.


Klüberfluid B-F 2 Ultra is used for the running-in lubrication of new, open drives by means of immersion, transfer, circulation and spray lubrication, or for tooth flank correction of large gear drives that have been in use for some time.

The use of Klüberfluid B-F 2 Ultra is not subject to any limitations regarding the size or power of the drives. A peripheral speed of 8.5 m/s should not be exceeded. Such drives are primarily to be found in rotary kilns, tubular mills and similar machinery in the cement, lime, gypsum and chemical industries and the mining sector. Klüberfluid B-F 2 Ultra must not be used for plain or rolling bearings.

Application notes

In immersion lubrication, Klüberfluid B-F 2 Ultra is taken up directly by the tooth flanks as they pass through the oil bath (forced lubrication, immersion depth max. half the tooth depth).

If the drive is fitted with a circulation lubrication system (e.g. Klübermatic PA), the lubricant will reach the tooth flanks through a lubricant pump and filters.

If Klüberfluid B-F 2 Ultra is applied by automatic spray systems, lubrication is permanent or nearly permanent (very short spray intervals).

Besides these lubrication methods, manual application by handheld lubrication equipment (Klübermatic KD) or brush is also possible.

The specific lubricant quantities as well as the total quantity can be taken from diagrams (contained in Klüber brochure
“Lubrication of large gear drives”, page 22).

Please stir Klüberfluid B-F 2 Ultra thoroughly before use as oil may separate off at the surface during storage in the closed or open container. Any oil separation at the surface will not affect the usability and effect of the product

NOTE: This lubricant must not be used as an operational lubricant!
