Klüberoil 4 UH1-68 N Synthetic lubricating oils for food industry 200L

Synthetic lubricating oils for food and pharmaceutical industry.Klüberoil 4 UH1-68 N is a synthetic high-performance gear and multipurpose oil based on polyalphaolefin satisfying the growing requirements and increasing power density of modern gears.Klüberoil 4 UH1-68 N is based on high-grade raw materials and advanced additives, enabling maximum performance in the lubrication of all gear components.Klüberoil 4 UH1-68 N is registered as NSF H1 for use in the foodprocessing and pharmaceutical industries and complies with FDA 21 CFR Sec 178.3570. It was developed for incidental contact with products and packaging materials in the foodprocessing, cosmetics, pharmaceutical or animal feed industries. The use of Klüberoil 4 UH1-68 N can contribute to increase reliability of your production processes. Nevertheless it is recommended to conduct an additional risk analysis, e.g.HACCP.Klüberoil 4 UH1 N is certified according to ISO 21469, thus supporting compliance with hygienic requirements of your production.Klüberoil 4 UH1 N from ISO VG 68 to 680 clearly exceeds CLP requirements according to DIN 51517-3. Corresponding gears can be switched to Klüberoil 4 UH1 N without prior consultation provided the general application notes are observed.Gears are sufficiently protected against scuffing even at extremely high peak loads, vibrations or oscillations, or if no running-in was performed. The good wear protection of both gears and rolling bearings ensures that the service life calculated for the lubricated components is achieved, leading to lower maintenance and repair costs.Klüberoil 4 UH1-68 N offers a much longer service life than mineral and white oils due to the excellent ageing and oxidation resistance of the selected raw materials; thus service intervals can be extended and maintenance costs reduced. In certain applications, even lifetime lubrication is possible. The product’s low foaming tendency and anti-corrosive properties enable problem-free gear operation. Oil leakage leading to contamination is prevented due to the good compatibility withelastomers.The good viscosity-temperature behaviour supports the formation of a sufficient lubricant film across a wide service temperature range, even at elevated and high temperatures.Therefore, a single viscosity grade can cover both low and high temperatures in many applications.The optimised friction behaviour enabled by the carefully selected base oils reduces power loss and improves gear efficiency.Klüberoil 4 UH1-68 N is approved by SEW Eurodrive, Getriebebau Nord, Stöber Antriebstechnik, Lenze, Sumitomo, Bonfiglioli, Brevini, STM, Watt Drive, etc.By using Klüberoil 4 UH1 N you can benefit from a number of advantages that will help you save costs easily and efficiently.Benefits:Registered as NSF H1 and certified according to ISO 21469High scuffing protectionGood wear protection for gears and rolling bearingsGood shear stability for reliable lubricant film formationExcellent ageing and oxidation resistanceWide service temperature range due to good viscosity-temperature behaviourLow foaming tendencyEnergy savings due to optimised friction behaviourGood elastomer compatibilityApproved by numerous gear OEMsApplication:Klüberoil 4 UH1-68 N was developed for the lubrication of spur, bevel and worm gears subject to high loads, bearings, spindles, joints as well as lifting, drive and transport chains.Application notes:Klüberoil 4 UH1-68 N can be used for immersion, immersion circulation and injection lubrication. The use of drip-feed oilers, brushes, oil cans or suitable automatic lubricating systems is also possible. When using automatic lubricating systems, please note the manufacturer’s instructions regarding the maximum permissible viscosity. The low-viscosity varieties are also used for oil mist lubrication.Klüberoil 4 UH1 N is miscible with mineral oils and synthetic hydrocarbons. Prior to switchover, lubrication points should be cleaned, or gears or enclosed systems be flushed with the Klüberoil 4 UH1 N oil to be used. In view of the H1 requirements in the food-processing industry, any mixture with non-H1 lubricants during conversion has to be prevented.For use at permanent temperatures of 80 °C max., seals made of NBR may be used. For higher temperatures, seals made of FKM should be chosen. It should be noted that elastomers from one or several manufacturers can behave differently; therefore tests should be performed.For checking the contact pattern during running-in, the inspection paint Klübertop P 39-462 Spray (Art. No. 081295) can be used.Viscosity selection:When determining the oil viscosity for gear lubrication, the gear manufacturer’s instructions take priority. Only for applications where manufacturer’s instructions are not available, the suitable viscosity can be determined as laid down in the worksheet Hints for Practice – selection of oil viscosity for gears. To determine the correct oil viscosity for bearings, please observe the bearing manufacturer’s instructions.Due to the better viscosity-temperature behaviour of Klüberoil 4 UH1-68 N compared to mineral oils, the actual viscosity of the oil during operation differs and can be determined by means of the enclosed diagram.Product data: NSF-H1 registration 121 174 Upper service temperature 120 °C / 248 °F Density, based on DIN 51757) at 15 °C approx. 851 kg/m³ Kinematic viscosity, DIN 51562 pt. 01/ASTM D-445/ASTM D 7042, 40 °C approx. 68 mm²/s Kinematic viscosity, DIN 51562 pt. 01/ASTM D-445/ASTM D 7042, 100 °C approx. 11 mm²/s ISO viscosity grade, DIN ISO 3448 68 Viscosity index, DIN ISO 2909 >= 140 Foam test, ASTM-D 892, ISO 6247, sequence I/24 °C <= 100/10 ml Foam test, ASTM-D 892, ISO 6247, sequence II/ 93.5 °C <= 100/10 ml Foam test, ASTM D 892, ISO 6247, sequence III/24°C <= 100/10 ml Flash point, DIN EN ISO 2592, Cleveland, open-cup apparatus >= 200 °C Pour point, DIN ISO 3016 <= -36 °C Ageing properties, ASTM D 2893, increase in viscosity <= 6 % Copper corrosion, DIN EN ISO 2160, 24 h/100°C 1 - 100 corrosion degree Anticorrosive properties on steel, DIN ISO 7120, method A, steel, 24 h/60 °C no rust corrosion degree FZG scuffing test, DIN ISO 14635-1, A/8.3/90, scuffing load stage >= 12 FAG FE8 rolling bearing test, DIN 51819-3, D 7,5/80-80, wear of rolling element <= 30 mg FAG FE8 rolling bearing test, DIN 51819-3, D 7,5/80-80, wear of cage <= 200 mg Minimum shelf life from the date of manufacture - in a dry, frost-free place and in the unopened original container, approx. 24 months
