plate.
8. Warm up the grease slinger and push it onto the shaft.
9. Depending on the particular version, fix the bearing with a locking ring or shaft nut.
10.Support the rotor when installing the bearing housing or bearing end shield.
11.Use a suitable sealant when assembling.
12.Assemble the bearing shield or bearing housing together with the bearing shield.
13.Install the outer bearing cover, if available.
14.Install the sealing elements:
Sealing the bearings
Note the following details:
• Shaft sealing rings are used to seal machines at the rotor shaft.
– For V rings, comply with the assembly dimension.
• Use the specified bearings.
• Ensure that the bearing sealing disks are in the correct position.
• Insert the elements for bearing preloading at the correct end.
• Fixed bearings can have a locking ring or bearing cover.
• Seal the bearing cap screws with the appropriate gaskets or with grease.
• Do not interchange the position of the bearing covers (DE and NDE or inner and outer).
Danger as a result of rotor falling out
If the motor is in a vertical position, the rotor can fall out while work is being performed on the
locating bearing. This can result in death, serious injury or damage.
• Support or unload the rotor when carrying out work with the machine in a vertical position.
