Klüber Barrierta GTE 403

Klüber Barrierta GTE 403 Is a high-temperature lubricating grease.


Benefits for your application


– Long-term and lifetime lubricant for rolling bearings
– Wide service temperature range
– Neutral towards most elastomers and plastics
– Resistant to water and chemicals
– For the lubrication of contacts, e.g. plug-in contacts



BARRIERTA GTE 403 is a synthetic high-temperature lubricating grease based on perfluorinated polyether oil and PTFE.

BARRIERTA GTE 403 is resistant to chemicals and aggressive media such as concentrated acids, alkaline solutions and organic solvents  (except for fluorinated hydrocarbon solvents, strong bases, earth/alkali metals and Lewis acids). It is neutral to most elastomers and plastics.



BARRIERTA GTE 403 is especially suitable for long-term and lifetime lubrication of rolling bearings subject to extreme temperatures, for example electric motor bearings (Siemens electric motor test at 150 °C: > 5000 h) or piston pins in dry running compressors. Furthermore it can be used for the lubrication of electric contacts, e.g. gold, silver and tin plug-in contacts. BARRIERTA GTE 403 is also used for plastic/plastic combinations in the optical and optoelectronic industries.

Application notes


Bearings should be equipped with cap or seal in order to achieve long service life. Prior to the first application, clean all friction points with white spirit 180/210 and then with Klüberalfa XZ 3-1.Upon cleaning apply clean dry compressed air or hot air to remove any remaining white spirit residues. For initial lubrication, the friction point must be clean and bright (i.e. free from oil, grease or perspiration) and free from particles. To remove lubricants based on perfluorinated polyether oil, such as BARRIERTA, use the solvent and cleaning agent Klüberalfa XZ 3-1.
