Klüberplex AG 11-462 and BEM 41-141 Greases
Description
Specialty lubricants for the wind energy industry, Klüberplex AG 11-462 and Klüberplex BEM 41-141 meet the extreme demands placed on wind turbines and their component
Klüberplex AG 11-462 offers effective corrosion and wear protection as well as provides a high load-carrying capacity.
Klüberplex BEM 41-141 is a high-performance grease designed for use in bearings subject to high loads and temperatures. The lubricant reduces frictional resistance, resulting in lower operating temperatures and reduced lubricant consumption. Klüberplex BEM 41-141 offers good wear protection for longer component service life and is suitable for a variety of applications, including the lubrication of generator bearings in wind power stations.
Specs
Klüberplex AG 11-462:
- Reduced maintenance needs
- Low contamination of machine environment due to use of white solid lubricants and low lubricant consumption
- Very good adhesion even at low temperatures
- Product streamlining possible as the product is suitable for gear rim/pinion drives and bearings
- Improved component performance
- Less wear due to selected solid lubricants and additives
- Very good corrosion protection also when exposed to salt water
Klüberplex BEM 41-141:
- Trouble-free operation due to wide service temperature with good pumbability and metering via centralised lubrication systems
- Longer service life of rolling bearings due to good wear protection characteristics also under vibration conditions
- Higher reliability of wind power stations due to good grease distribution and oil separation
- Low frictional resistance and reduced component temperature
- Reduced wear due to excellent lubricity
- Easy changeover to Klüberplex BEM 41-141 as the lubricant is miscible with other greases
