kluberplex bem 34-131 n

In wind turbine generators, the lifetime of rolling bearings and service intervals can be extended with the right lubricant. Klüberplex BEM 34-131 N is a long-term lubricating grease offering high loadcarrying capacity and very good corrosion protection. Also during downtime. Klüberplex BEM 34-131 N enables long grease life and is compatible with various lubrication systems.

Klüberplex BEM 34-131 N is used for the lubrication of generator bearings in wind turbines. It can also be used for rolling bearings subject to oscillation, high loads and vibration. Klüberplex BEM 34- 131 N is a grease for long-term or lifetime lubrication of different rolling bearing types and applications subject to various operating conditions.
These may be found in: Hub units (wheel bearings in cars), shock absorber bearings, fans, electric motors, water pumps, paper-making machines (wetprocessing zone), conveyors, universal joint bushes, linear guides and ball screws subject to micro movement.

  • Increased reliability of wind turbine generators due to excellent corrosion protection, good resistance to weather and a wide service temperature range
  • Longer service life of rolling bearings due to good wear protection, also under vibration and oscillation
  • Reliable operation due to good pumpability and metering via centralised lubrication systems
  • Low frictional resistance, reduced wear and component temperature due to excellent lubricity
