Removing the labyrinth sealing ring
Before the rolling bearing is uninstalled, the labyrinth sealing ring must be removed. For the

ring at the drive end and the non-drive end.
The labyrinth sealing ring is fixed with three set screws that are separably secured with
cement such as Loctite 243.

engagement to avoid clamping to the shaft or damaging the thread.
