In an aircraft sustaining rotor, a pivotal blade mounting including relatively rotatable blade mounting parts subject to axial load, a torsionally yieldable member interconnecting said parts to take said axial load, and a thrust bearing interposed in series in the connection of said member with said parts, the thrust bearing having a higher frictional moment than the resistance to torsional yielding of said member within a limited range of angular displacement of the blade mounting parts when under normal flight loading.
