Bearing land diameters are given by the
maximum outside diameter of the inner ring (li) and the minimum
inside diameter of the outer ring (lo). Bearing land diameters are
given in the individual bearing tables.
Inner land diameter = li
Outer land diameter
=lo
Bearing pitch diameter dp is the diameter
of the circle that the center point of a ball travels during
rotation of a bearing.
li + lo

Note: For pitch
diameter calculations, use the land diameter values from the open (unshielded) bearing tables.

FREE ANGLE OF MISALIGNMENT
The free angle of misalignment (?f) of a bearing is
the maximum angle between the inner race and outer race axes freely
allowed by the bearing. If a bearing is misaligned such that this
angle is exceeded, then damage and premature failure can occur.
