Horizontal Alignment
Standard
The combination of offset and angle is a direct indication of the alignment condi-
tion. Optimum alignment occurs when offset and angle are zero. In most cases,
that degree of accuracy is not practical. For that reason, tolerances are used to set
an achievable goal. Emerson’s recommended tolerances (referenced to RPMs) are
listed in the table below.
