WebAug 11, 2006 · A difficult consequence of small-scale turbomachinery is an increased rotor speed, in the order of 500 000 rpm and higher, turning bearing design into a challenging task. Air bearings are the only bearing type able to withstand the severe conditions of high speed and high temperature. WebApr 22, 2024 · One of the most notable considerations when selecting a high-speed grease is the temperature at which the bearing will operate. One can ensure that selected grease will perform satisfactorily at elevated temperatures by checking the dropping point of the grease. A higher drop point is important for bearings operating at elevated temperatures. how many nba players 20 seasons
