Installing the active parts of the bearings
NOTICE
We recommend that you label the components that comprise the active part of the bearing
before dismantling them, in order to ensure correct reassembly.
NOTICE
When dismantling and assembling the bearings, make sure that you match up the
components correctly (bearings, preloading springs, equalizing rings, caps with different
centering length, etc.), especially when the bearings at the drive end and non-drive end are
the same size.
NOTICE
Label the components before dismantling.
NOTICE
Whenever you work on the locating bearing when the three-phase motor is in its vertical
position, support/unload the rotor.
