Klübersynth EG 4-460  Klübersynth EG 4 oils Synthetic high-performance gear oils Description The Klübersynth EG 4 oils are fully synthetic high-performance gear oils conforming to the demands of CLP ａnd AGMA. They are also mineral oil miscible. In addition to their excellent anticorrosion ａnd anti-wear properties, these oils are very resistant to ageing ａnd oxidation ａnd offer exceptional service at low temperatures. They also show a low tendency to foam. In the FZG test (A10/16,6R/90) a scuffing load capacity of GL 4 was achieved. Fields of application The Klübersynth EG 4 oils are particularly suitable for lubricating friction points subject to high loads over a wide temperature range. The oils can be used to lubricate spur, bevel ａnd worm gears. Klübersynth EG 4 oils are stable under shear stress ａnd offer excellent demulsifying properties. The oils react on the whole neutrally to common seal materials such as NBR or FPM ａnd lacquers. Care should nevertheless be taken, as elastomers from different manufacturers can behave differently. Therefore the data given in the „compatibility with elastomers“ section should be used for reference purposes only. For this reason a compatibility test should always be carried out with the elastomers which are actually used. Application notes The oils can be applied using the immersion, immersion circulation ａnd injection methods. Total loss lubrication is possible with drip-feed, brush or oil feeder application. It is possible to apply the oils automatically, but attention should be paid to the maximum processable viscosity value in the manufacturer’s instructions. Viscosity selection for rolling bearings ａnd gears To determine the correct oil viscosity please refer to the bearing manufacturer’s instructions or worksheet 3 from the Society of Tribology (GfT). The gear manufacturer’s instructions always take priority when determining the oil viscosity for gears. If instructions are not available from the gear manufacturer then the viscosity can be determined from the „Klübersynth EG 4 oils – Selection of oil viscosity for gears“ work sheet. Operating temperature range Operating temperature values are reference values which have been established according to the lubricant structure, desired application ａnd application engineering. • Gear ａnd chain lubrication by immersion: Klübersynth EG 4-150 /...220 from approx. -35 °C to 140 °C Klübersynth EG 4-320 /...460 from approx. -30 °C to 140 °C Klübersynth EG 4-680 from approx. -25 °C to 140 °C Klübersynth EG 4-1000 from approx. -15 °C to 120 °C Storage The minimum shelf life is approx. 36 months when stored carefully in a dry place ａnd in closed original containers.
