Spherical Roller Bearing: Managing Misalignment
Managing and compensating for misalignment is crucial to ensure the efficient operation of the bearing. Here are some steps and considerations for managing misalignment in spherical roller bearings: Bearing Design . Spherical roller bearings are inherently self-aligning, which means they can tolerate some degree of misalignment.

Misalignment is when rotational center lines of coupled shafts are not collinear. High 2xTS peak characterizes offset misalignment; a high 1xTS signifies angular misalignment, though both frequently combine to cause1xTS and 3xTS in the spectrum. Highest amplitudes typically occur in the radial direction for horizontally mounted equipment;
