Klüberfluid C-F 8 ULTRA is a newly developed lubricant especially for use on medium-size to large girth gear drives. It is based on a mixture of synthetic hydrocarbons and mineral oil.

Klüberfluid C-F 8 ULTRA provides extremely good adhesion, resistance to high pressure and exceptional wear protection. It is suitable for use at component temperatures up to 120 °C.

Klüberfluid C-F 8 ULTRA is free from bitumen, solvents, heavy metals, chlorine and solid lubricants.

Klüberfluid C-F 8 ULTRA corresponds to ANSI/AGMA 9005- E02 annex D.


Klüberfluid C-F 8 ULTRA can be applied by immersion, transfer paddle wheel, pressure fed circulation and total loss spray lubrication systems. It can be used with all gear sizes and power ratings. A peripheral speed of 8 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 found in sugar and paper production as well as in the marine and offshore sector

Application notes

When applied by immersion, Klüberfluid C-F 8 ULTRA is directly transferred onto the tooth flanks. The Klübermatic PA circulation lubrication system can also be employed to recirculate the lubricant under pressure onto the tooth flanks.

Klüberfluid C-F 8 ULTRA may also be applied via other customary spray systems.

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