272 Tribology in machine design

Accumulation of tolerances which is quite usual when a machine is built up
from a number of parts can result in large misalignments between housing
bores.
The level of noise and vibration produced by a rolling-contact bearing is
an extremely good indicator of its quality and condition. Rolling bearings
are available in a range of precision grades and the selection of higher
grades of precision is an effective way to obtain low vibration levels,
particularly in the low-frequency range. It should be remembered, however,
that the machine to which the bearing is going to be fitted should be
manufactured to a similar level of precision.
