In the case of thrust bearings, axial vibrations correlate with thrust pulsations which could cause damage to the metal liners of sleeve bearings or to parts o

Where bearings have no axial limiting constructions, a less exacting requirement may be acceptable. All such cases should be subject to prior agreement between manufacturer and pu
