Klüber BARRIERTA L 55/1 High-temperature long-term grease 800g

High-temperature long-term greasesYour 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.Size: 800g cartridgeAvailable in 180g glas, 800g cartridge, 1kg can, 10kg bucketBenefits for your application: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 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 Application:Rolling and plain bearings subject to high temperatures.One of the wellknown 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 bearings     -Calender bearings     -Fan bearings     -Chain bearings in film stretching stenters BARRIERTA L 55/1 is most frequently used for initial and longterm lubrication. For relubrication softer grades of NLGI class 1 or lower are recommended.Product data:Article number90042NSF-H1 registration129 561Chemical composition, type of oilPFPEChemical composition, solid lubricantPTFELower service temperature-40 °C / -40 °FUpper service temperature260 °C / 500 °FColour spacewhiteDensity at 20 °Capprox. 1,95 g/cm³NLGI grade, DIN 518181Shear viscosity at 25 °C, shear rate 300 s-1, equipment: rotational viscometer, lower limit value4 000 mPasShear viscosity at 25°C, shear rate 300 s-1, equipment:rotational viscometer, upper limit value8 000 mPasKinematic viscosity of the base oil, DIN 51562 pt. 01/ ASTM D-445/ASTM D 7042, 40 °Capprox. 420 mm²/sKinematic viscosity of the base oil, DIN 51562 pt. 01/ ASTM D-445/ASTM D 7042, 100 °Capprox. 40 mm²/sCorrosion inhibiting properties of lubricating greases, DIN 51802, (SKF-EMCOR), test duration: 1 week, distilled water<= 1 corrosion degreeFlow pressure of lubricating greases, DIN 51805, test temperature: -40 °C<= 1 400 mbarFour-ball tester, welding load, DIN 51350 pt. 04>= 7 000 NSpeed factor (n x dm)approx. 300 000 mm/minMinimum shelf life from the date of manufacture – in a dry, frost-free place and in the unopened original container, approx.60 months  Information on product safety (Manufacturer, Contact)KLÜBER LUBRICATION MÜNCHEN GMBH & CO.
