Main Characteristics	The wiping at opposite sides of the top and bottom halves of the bearing shows misalignment causing breakdown of the oil film by edge loading.
Cause	A similar result could occur by running with a tapered shaft, but in this case the damage would be on the same side of each bearing half.
Note	The low melting point and strength of white metal (compatibility) are valuable properties, allowing it to wipe or deform to compensate for a limited amount of misalignment.
