WebBearing Damage: Wiping - Waukesha Bearings A wiped bearing surface may be due to excessive load at start-up/run-down, insufficient lubricant, operational overload, loss of clearance, or misalignment. English Chinese About About Us Engineering & Technology WebA bearing arrangement supports and locates a shaft, radially and axially, relative to other components such as housings. Typically, two bearing supports are required to position a shaft. Depending on certain requirements, such as stiffness or load directions, a bearing support may consist of one or more bearings.
WebBearing misalignment: as already mentioned in the chapter about misalignment, spectral signatures are characterized by the presence of vibration at various harmonics of the rotating frequency, with the amplitude being the most significant at N B x RPM, where N B is the number of rolling elements in the bearing.
