Manufacturer's description

Shell GadusRail S4 WFB 000 is a synthetic ester based grease designed for usage in onboard lubricators in the railway business requiring a thin grease meeting EN 16028 requirements. Good anti-wear and anti-corrosive properties are combined with pump ability in a wide range of temperatures.

Applications

  • On board lubrication of trams and railways, for electrically or air pressure operated lubricators.
  • Nozzle selection according OEM recommendation. Volume range of 10 - 40 mg

Performance & benefits

  • Good anticorrosive properties
  • Favorable flow property at low temperatures
  • Compatible with standard seals and painting, as normally used with mineral oil based products
  • Biodegradable as per the requirements of EU Ecolabel (EEL). At least 80% by mass of this greases’ components are ready biodegradability, achieving a passing result of ≥60% according to OECD 301B.
  • Highly adhesive coating

Standards & approvals

  • EU Ecolabel

    The European Union's voluntary ecolabel, certifying that a product, including lubricants, meets reduced-environmental-impact criteria across its life cycle.

  • SS 15 54 70

    SS 15 54 70 — environmental requirements for greases (Sweden)

    The counterpart of the Swedish SS 15 54 34 standard applied to greases: high biodegradability, low aquatic toxicity, and no environmentally hazardous classification.

  • OECD 301B

    OECD 301B biodegradability above 60 %

    A test result rather than a norm: OECD 301B measures the carbon dioxide evolved over 28 days. Above 60 % counts as "readily biodegradable", the threshold the environmental labels require.
