KLUBERSYNTH UH1 6

Synthetic high-performance gear oil for the food-processing and pharmaceutical industries with KlüberComp Lube Technology.

Klübersynth UH1 6 is a synthetic high-performance gear oil based on polyglycol satisfying the growing requirements and increasing power density of modern gears. Klübersynth UH1 6 includes KlüberComp Lube Technology*, i.e. it is based on especially highgrade raw materials and advanced additives, enabling maximum performance in the lubrication of all gear components.

Klübersynth UH1 6 oils 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 Klübersynth UH1 6 oils can contribute to increase reliability of your production processes. We nevertheless recommend conducting an additional risk analysis, e.g. HACCP.

Klübersynth UH1 6 is certified according to ISO 21469, thus supporting compliance with hygienic requirements of your production.

Klübersynth UH1 6 clearly exceeds CLP requirements according to DIN 51517-3. Corresponding gears can be switched to Klübersynth UH1 6 without prior consultation with the gear manufacturer provided the general application notes are observed.

Klübersynth UH1 6 offers high scuffing load capacity. Gears are sufficiently protected against scuffing even at extremely high peak loads, vibrations or oscillations, or if no running-in was performed.

The excellent 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. The oil's high micropitting resistance of GFT ≥ 10 according to FVA 54/7 offers sufficient protection to gears that are subject to high loads and would normally be susceptible to this type of damage.

Klübersynth UH1 6 offers a much longer service life than mineral 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 anticorrosive properties enable problem-free gear operation. Freudenberg seals made of 72 NBR 902, 75 FKM 585, 75 FKM 260466 and 75 FKM 170055 are resistant to Klübersynth UH1 6. Leakage and oil contamination are prevented.

The excellent 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 based on polyglycol reduces power loss and improves gear efficiency, especially in worm gears. Due to the optimised additives, wear values are reduced and a very low wear intensity according to DIN 3996 (calculation of load capacity of worm gears) is achieved.

Klübersynth UH1 6 is approved by Siemens-Flender, Siemens Geared Motors, SEW Eurodrive, Getriebebau Nord, Stöber Antriebstechnik, Lenze, ZAE Antriebssysteme, Baldor, Boston Gear, Bonfiglioli, Watt Drive, etc.

By using Klübersynth UH1 6 you can benefit from a number of advantages that will help you save costs easily and efficiently. We look forward to hearing from you. * For further information, please see our flyer: KlüberComp Lube Technology – Gear oils meeting the highest requirements

Klübersynth UH1 6 oil is used for the lubrication of highly loaded spur, bevel and planetary gears, rolling and plain bearings as well as all types of toothed couplings, especially when exposed to high temperatures.
Klübersynth UH1 6 oil was especially developed for the lubrication of worm gears with steel/bronze pairings. It can also be used for the lubrication of lifting, drive and transport chains.
Klübersynth UH1 6 can be applied by means of immersion, immersion circulation or injection.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.
Klübersynth UH1 6 is not miscible with mineral oil or synthetic hydrocarbons. Prior to switchover, lubrication points should be cleaned, or gears or enclosed systems be flushed with the Klübersynth UH 1 6 oil to be used.
Klübersynth UH1 6 is neutral towards ferrous and nearly all nonferrous metals. There may be increased wear when the contact surfaces of design elements made of aluminium or aluminium alloys are exposed to dynamic loads. If necessary, preliminary wear tests should be carried out.
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.
When applying Klübersynth UH1 6 oil we recommend the use of two-component paints (reaction paints) for interior coating. Oil gauge glasses should preferably be made of natural glass or polyamide materials. Other transparent plastics, e.g. Plexiglas, have a tendency to crack under stress. The suitability of materials used in contact with Klübersynth UH 1 6 oil should be tested, especially prior to series application.
For checking the contact pattern during running-in, the inspection paint Klübertop P 39-362 Spray (Art. No. 081295) can be used.
