Low-noise, high-precision running is often of crucial importance for bearings, e.g. in electric motors, fans and precision-engineered mechanical components. Nowadays, low-noise specialty lubricating greases enable many industrial and engineering applications to be effectively mastered. For selecting the right lubricant, however, the individual components involved pose additional requirements: aspects like elastomer compatibility, thermal stability, speed or the bearing’s running time have to be factored in. Depending on the operating conditions concerned, designers can utilize different grease concepts, and underpin their choice with dependable data on the behavior of selected lubricating greases, as validated by test rig studies. In order to maximize rolling bearing lifetimes, precise knowledge of the lubricant’s performance features is indispensable.
