Klüberfluid C-F 7 Ultra is a newly developed operational lubricant based on synthetic oils, especially for use on medium to large girth gear drives. It provides good adhesion, resistance to high pressure and wear protection and can be used at component temperatures up to 120°C.

Klüberfluid C-F 7 Ultra is free of bitumen, raw materials containing solvents, heavy metals or chlorine and solid lubricants.

Klüberfluid C-F 7 meets the requirements set forth in ANSI/ AGMA 9005-E02 Annex D-2. This product was especially developed with a view to low-temperature applications.


Klüberfluid C-F 7 Ultra can be applied by immersion, transfer paddle wheel, circulation or spray lubrication systems. It can be used with all gear sizes and power ratings. A peripheral speed of 10 m/s however should not be exceeded. Such drives are mostly found in rotary kilns, tube mills, drums and similar machinery used in the cement, lime, gypsum, mining and chemical industries as well as in coal-fired power stations. Further applications are in sugar and paper production as well as in the marine and offshore sector.

Application notes

When applied by immersion, Klüberfluid C-F 7 Ultra is directly transferred onto the tooth flanks of the immersing wheel. The  Klübermatic PA circulation lubrication system can also be employed to recirculate the lubricant under pressure onto the tooth flanks.
Klüberfluid C-F 7 Ultra may also be applied via the customary spray systems.

The lubricant film on the tooth flanks can be made visible by using a UV lamp with a wavelength of 366 nm.
