ARVINA XR - extreme performance bearing greases

ARVINA XR - extreme performance bearing greases

MOLYSLIP ARVINA XR greases are fully synthetic, perfluorinated greases designed for bearings operating in extremes of temperature and aggressive chemical environments.

The optimised base oil, thickener and additive system combine to deliver outstanding resistance to thermo-oxidative degradation at temperatures up to 280°C. ARVINA XR greases have excellent resistance to most aggressive chemicals such as acids, alkalis, solvents and oxidising agents allowing them to be used where conventional products will fail.

MOLYSLIP ARVINA XR greases are suitable for use in plain, ball and roller bearings, slides, gears, pins/bushes and valve mechanisms operating in the temperature range of -30°C to +280°C.

Features and benefits

  • Excellent high temperature capability up to 280°C
  • Outstanding chemical resistance
  • Highly effective lubrication and wear protection
  • Significantly extended relubrication intervals compared to conventional greases

Instructions for use

MOLYSLIP ARVINA XR greases can be applied manually, via a standard grease gun or via a central lubricating system (depending on the grade selected).

As with all greases used for the first time, check compatibility with the grease used previously and if necessary purge and clean bearings prior to application. If the previous grease was not perfluorinated then extreme care should be taken to thoroughly degrease using a suitable solvent. ARVINA XR products are not compatible with conventional mineral or synthetic oil greases.
