KLUBER BARRIERTA L 55/2 High-temperature long-term greases

Klüber Lubrication, a global leader in specialty lubricants, has expanded its renowned BARRIERTA® line with the high-performance BARRIERTA® L 55/2, tailored for long-term, high-temperature applications across various critical industries.

Formulated with perfluorinated polyether oil (PFPE) and polytetrafluoroethylene (PTFE), BARRIERTA L 55/2 is engineered to deliver exceptional performance in rolling and plain bearings, slideways, and other tribological points subjected to continuous heat exposure up to 260°C. The grease exhibits a low evaporation rate, ensuring extended relubrication intervals and reducing maintenance costs.

One of the key advantages of BARRIERTA L 55/2 lies in its compatibility with most elastomers and plastics, including FKM materials, making it ideal for sensitive environments such as textile machinery, electric motors, dryers, fans, baking machines, and even vacuum pumps. Furthermore, the product is resistant to aggressive media, including acids, alkaline solutions, and solvents (excluding fluorinated hydrocarbons and strong bases).

The product meets stringent industry requirements and is NSF H1 registered (No. 129400), confirming its suitability for incidental food contact applications within the food processing industry.
