Although bearing
numbering
is (and should be) the primary identifier of the position of the reading,
bearing names are often used as well. Since there are a variety
of common names used for naming the different bearing positions - several
for each position, in fact - a list of the common ones is put forth here.
There are no right or wrong ones - the only important aspect is complete
consistency in your usage.

You may have applications
that do not fall neatly into the 4-bearing machine category. Long drive
lines with dozens of bearings, gearboxes like the one shown on the previous
page, multi-stage machines, etc. may each require their own unique solution
for bearing naming. In the case of a long drive line, the bearing may be
named to coincide with the piece of equipment along that drive line that
bearing is closest to. Conversely, you may decide to rely strictly on position
numbers in that case and not use position names at all. Terms
such as "Intermediate Shaft" may be used. There is no single, universal
naming convention that will apply to all machine configurations. Remember
