- Klübersynth GH 6 is a synthetic high-performance gear and high-temperature oil based on polyglycol satisfying the growing requirements and increasing power density of modern gears.
- It includes KlüberComp Lube Technology*, i.e. it is based on especially high-grade raw materials and advanced additives, enabling maximum performance in the lubrication of all gear components.
- Temperature range: -25°C to +160°C
- Volume: 5 l canister
- Also available in: 20 Liter, 200 l drum
Benefits for your application
- High scuffing protection
- Excellent wear protection for gears and rolling bearings
- Good shear stability for reliable lubricant film formation
- High micropitting resistance
- Optimised for the lubrication of worm gears
- Excellent ageing and oxidation resistance
- Wide service temperature range due to good viscosity-temperature behaviour
- Low foaming tendency
- Energy savings due to optimised friction behaviour
- Good elastomer compatibility
- Approvals by numerous gear OEMs
Applications
- Klübersynth GH 6 oil was especially developed for the lubrication of worm gears with steel/bronze or steel/grey cast iron pairings.
- Klübersynth GH 6 oil is also used for the lubrication of bevel and spur gears, rolling and plain bearings as well as all types of toothed couplings, especially when exposed to high temperatures. It can also be used for the lubrication of lifting, drive and transport chains.
Application notes
- Klübersynth GH 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 GH 6 is not miscible with mineral oil or synthetic hydrocarbons. Prior to switchover, lubrication points should be cleaned, or gears or enclosed lubrication systems be flushed with the Klübersynth GH 6 oil to be used.
