Corresponding gears can be switched to Klübersynth GH 6 oils without prior consultation with the gear manufacturer provided the general application notes are observed. • As of ISO VG 220 the scuffing load stage API GL 4 is achieved. Gears are sufficiently protected against scuffing even under high peak loads. • Much longer service life than mineral oils due to the excellent ageing ａnd oxidation resistance of the base oil; thus maintenance intervals can be extended ａnd in certain cases even lifetime lubrication is possible • Owing to the wide service temperature range a single viscosity grade can cover both low ａnd high temperatures in many applications • The optimum friction behavior of the polyglycol base oil reduces power losses ａnd improves efficiency • The good wear protection of both gears ａnd rolling bearings ensures that the service life calculated for the lubricated components is achieved • The excellent viscosity-temperature behavior supports the formation of a sufficient lubricating film even at elevated ａnd high temperatures • Seals made of 72 NBR 902 or 75 FKM 585 are resistant Klübersynth GH 6 oils. Leakage ａnd contamination are prevented. • Approved by Flender, SEW Eurodrive, Getriebebau Nord, Stöber Antriebstechnik, Lenze, ZAE Antriebstechnik, Bonfiglioli, Rossi Motoriduttori, Motovario, Moventas, etc. Application Klübersynth GH 6 oils were especially developed for the lubrication of worm gears with steel/bronze pairings. The polyglycol base oils ａnd special additives reduce the friction coefficient ａnd provide low wear values, which is a clear advantage in these applications. Klübersynth GH 6 oils achieve a particularly low wear intensity according to DIN 3996 (calculation of load capacity of worm gears). Klübersynth GH 6 oils are also used for the lubrication of bevel ａnd spur gears, rolling ａnd plain bearings as well as all types of denture couplings, especially when exposed to high temperatures. Klübersynth GH 6 oils can also be used for the lubrication of lifting, drive ａnd transport chains. Description Klübersynth GH 6 oils are gear oils on a polyglycol basis. They have a high scuffing load capacity ａnd micro-pitting resistance. These oils have also proved their good wear protection in rolling bearings on the FAG FE 8 test rig for gear oils. Klübersynth GH 6 oils stand out for their excellent ageing ａnd oxidation resistance, good viscosity-temperature behavior ａnd very good thermal stability.

Klübersynth GH 6 oils are not miscible with mineral oils ａnd synthetic hydrocarbons. Application notes We recommend cleaning the lubrication points or rinsing gears with the Klübersynth GH 6 oil which will be used after conversion. Klübersynth GH 6 oils are neutral towards ferrous metals ａnd almost 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 tests should be carried out. For permanent temperatures up to 80 °C seals made of 72 NBR 902 may be used. For higher temperatures, we recommend to use seals made of 75 FKM 585. It should be noted that elastomers from one or several manufacturers can behave differently; therefore tests should be performed. When applying Klübersynth GH 6 oils 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 GH 6 oils should be tested, especially prior to series application. Viscosity selection When determining the oil viscosity for gears, the manufacturer＇s instructions take priority. In cases where there are no gear manufacturer＇s instructions, the viscosity can be selected in accordance with the enclosed worksheet "Klübersynth GH 6 oils – selection of oil viscosity for gears". To determine the correct oil viscosity for bearings, please observe the bearing manufacturer＇s instructions. For determining the actual viscosity, please refer to the enclosed viscosity-temperature diagram indicating the differing viscositytemperature behavior of Klübersynth GH 6 oils as compared to mineral oils. Minimum shelf life The minimum shelf life is approx. 36 months if the product is stored in its unopened original container in a dry, frost-free place.
