OVERVIEW
Two bearings support and locate a shaft
AXIAL, MIXED FLOW, TUBULAR CENTRIFUGAL FANS axially and radially in relation to the housing,
which is stationary. There is “fixed” side and a
“floating” side. The fixed side controls the shaft
axially. The floating side has more freedom of
movement (floating) to help compensate for
thermal expansion or contraction of shaft.
