Robustness of Cryogenic Hybrid Journal Bearings

Robustness of Cryogenic Hybrid Journal Bearings

In the present study, a nine-recess hybrid journal bearing (HJB) having a Young Leaf Mark recess was operated at a rotational speed of up to 75,000 rpm using the cryogenic journal bearing test apparatus at JAXA, to clarify an onset speed of the rotor instability supported by the cryogenic HJBs.
