Today the name of BARRIERTA is widely regarded as synonymous with long-term stability and thermal resistance. Specifically made raw materials and continued development have made BARRIERTA products the first choice of lubrication experts in many sectors worldwide.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.BARRIERTA L 55/0-3 are NSF H1 registered and therefore comply with FDA 21 CFR § 178.3570. The lubricants were developed for incidental contact with products and packaging materials in the food-processing, cosmetics, pharmaceutical or animal feed industries. 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.ApplicationRolling and plain bearings subject to high temperaturesOne 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:conveyors (load and turn rollers)kiln cart wheel bearingscalender bearingsfan bearingschain bearings in film stretching stentersBARRIERTA 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 mediaBARRIERTA 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 invalves, fittings and installations e.g. in the chemical industrypneumatic componentslevel gauges, e.g. for fuels or chemicalsseals (static, dynamic)extraction systemsFood-processing and pharmaceutical industriesAll 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 productionBARRIERTA L 55 series High-temperature long-term greasesProduct informationplant. You will find further information on ISO Standard 21469 on our website www.klueber.com.White-coloured BARRIERTA L 55 special lubricants can therefore also be used on friction points where occasional 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 inautomatic baking ovenscooking or frying linesconveyor systemsPlastic-plastic friction pointsBARRIERTA 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 notesFor optimum results we recommend cleaning all friction points with white spirit 180/210 and then with Kl?beralfa XZ 3-1 prior toinitial 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 technical sales staff for details of ?best practice? with BARRIERTA L 55 lubricants to ensure longest lifetimes and highest performance outcomes are achieved.Minimum shelf lifeThe minimum shelf life is approx. 60 months if the product is stored in its unopened original container in a dry, frost-free place.Material safety data sheetsMaterial safety data sheets can be downloaded or requested via our website www.klueber.com.
