Expansion Units Options
Additional Options
Axial shaft expansion is compensated by a non-expansion (xed) and
expansion (oat) arrangement. Many bearings are offered in both xed
and oat arrangements and have identical mounting dimensions. It is
recommended to use both units on one shaft in high temperature applications
to help account for linear shaft expansion. For more information see page
G-249 in the Mounted Ball Bearing Engineering section.
