Klüberlub BE 71-501 is a light-coloured special lubricating grease for highly loaded rolling and plain bearings. It offers good compatibility with nonferrous metals, such as those used as plain bearing materials. Due to its special formulation and solid lubricants, wear is low under rotating and oscillating motion and high impact loads. It is resistant to water and has a good sealing effect. The additives contained in this product enhance its ageing resistance.

Application
Klüberlub BE 71-501 can contribute to extending the service life of plain bearings where low-wear and low-friction operation is required under mixed friction conditions. This special grease meets the requirements in terms of reduced lubricant consumption and extended lubrication intervals in forging presses while maintaining a constant temperature level in the plain bearing. It can also be used for plain bearings subject to high loads in the plastics processing industry and building machines (e.g. ring-roll mills) and in construction machines. Owing to the good results achieved on rolling bearing test rigs and the good pumpability of the grease in commercial central lubrication systems, Klüberlub BE 71-501 is also suitable for high-temperature applications, especially in the steel industry (e.g. ring-roller mills) and woodworking industry (e.g. rolling bearings in pelleting presses).
Application Notes
Klüberlub BE 71-501 can be applied by means of central lubrication systems or by brush, spatula, grease gun and automatic metering devices. When switching to Klüberlub BE 71-501, the lubricant consumption should be reduced step by step in order to ensure that used lubricant, wear particles and impurities are completely removed from the bearing.
