Klüber BARRIERTA L 55/1

High-temperature long-term greases

Application Klüber BARRIERTA L 55/1

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: – conveyors (load and turn rollers) – kiln cart wheel bearings – calender bearings – fan bearings – chain bearings in film stretching stenters BARRIERTA L 55/2 is most frequently used for initial and longterm 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 – valves, fittings and installations e.g. in the chemical industry – pneumatic components – level gauges, e.g. for fuels or chemicals – seals (static, dynamic) – 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 – automatic baking ovens – cooking or frying lines – 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.
