Kluber BARRIERTA L 55/2 High-temperature long-term greases - cartridge FLEX 60ml, Kluber Lubrication PN: 0900130921

The Benefits

1. Higher machine availability and less need for maintenance: at very high operating temperatures up to 260 °C; under the influence of aggressive media and vapours; when used with plastics and sealing materials.
2. Reliable operation in numerous industries and component types: thanks to BARRIERTA base oils, which are made specifically to enable long-term stability; backed by a large number of approvals and references for various applications; four consistency classes to suit different applications.

The Solution

Your demanding application requires a high-quality lubricant of the highest quality and excellent lubrication properties. BARRIERTA is Europe's oldest high-quality brand of hightemperature lubricants based on perfluorinated polyether oil (PFPE). Today the name of BARRIERTA is widely regarded as synonymous with long-term stability and thermal resistance. We are committed to live up to this good reputation. BARRIERTA L55 series products are made from clearly specified raw materials and the production and quality of the end product is closely monitored. BARRIERTA L 55/0-3 series long-term greases offer excellent resistance to high temperature and aggressive media and at the same time compatibility with plastics and elastomers. The lubricants were developed for incidental contact with products and packaging materials in the food-processing, cosmetics, pharmaceutical or animal feed industries. BARRIERTA L 55/0-3 are NSF H1 registered and therefore comply with FDA 21 CFR § 178.3570. The use of BARRIERTA L 55/0-3 can contribute to increase reliability of your production processes. We nevertheless recommend conducting an additional risk analysis, e.g. HACCP.

Application

Rolling and plain bearings subject to high temperatures One of the well-known strengths of the BARRIERTA L 55 series is the products' suitability for the lubrication of bearings and guides operating under extreme temperatures. A low evaporation rate enables longest grease lives and hence longest relubrication intervals.

Typical applications include:

1. conveyors (load and turn rollers).
2. kiln cart wheel bearings.
3. calender bearings.
4. fan bearings.
5. chain bearings in film stretching stenters.

BARRIERTA L 55/2 is most frequently used for initial and long-term lubrication. For relubrication softer grades of NLGI class 1 or lower are recommended. Friction points under the influence of media BARRIERTA L 55 greases offer exceptionally long service lifetimes even when exposed to any of a large number of aggressive media such as concentrated acids, lyes, organic solvents or gases.

In addition to their resistance to media, BARRIERTA L 55/2 and BARRIERTA L 55/3 offer also good adhesion and a sealing effect, which makes them suitable for application in

1. valves, fittings and installations e.g. in the chemical industry.
2. pneumatic components.
3. level gauges, e.g. for fuels or chemicals.
4. seals (static, dynamic).
5. extraction systems.

Food-processing and pharmaceutical industries All BARRIERTA L 55 greases are registered as NSF-H1 and are therefore in compliance with FDA 21 CFR § 178.3570. The additional certification according to ISO 21469 supports the compliance with the hygienic requirements in your production plant.

White-coloured BARRIERTA L 55 special lubricants can therefore also be used on friction points where incidental contact with food products cannot be ruled out for technical reasons, e.g. in rolling and plain bearings and guides operating under high thermal loads in:

1. automatic baking ovens.
2. cooking or frying lines.
3. conveyor systems.

Plastic-plastic friction points BARRIERTA L 55 greases – irrespective of NLGI grade - are neutral towards the majority of plastic materials. Results of pertinent tests with fluoroelastomers can be found overleaf. We recommend testing lubricant compatibility with the materials in question prior to series application.

Application notes

For optimum results we recommend cleaning all friction points with white spirit 180/210 and then with Klüberalfa XZ 3-1 or Klüberalfa NH1 XZ 3-1 prior to initial lubrication. Subsequently, the friction points should be dried with clean dry compressed air or hot air to remove all solvent residues. The friction point must be free from oil, grease, perspiration and contamination particles before initial lubrication. Please contact our experts for details of "best practice" with BARRIERTA L 55 lubricants to ensure longest lifetimes and highest performance outcomes are achieved.
