12.3.13 General information on installing the shaft-mounted gearbox
NOTICE
Damage to shaft sealing rings caused by solvent
Avoid any contact of solvent or benzine with the shaft sealing rings.
NOTICE
Subjecting stress to the hollow shaft causes bearing failure
Skewing or stressing the hollow shaft increases the loading. This can cause bearing failure.
The hollow shaft must be ush with the machine shaft to avoid misalignment.
Do not subject the hollow shaft to axial and radial stress.
NOTICE
For shrink disks:
Lubricants in the area between the hollow shaft and machine shaft impair torque
transmission
Keep the bore in the hollow shaft and the machine shaft completely grease-free.
Do not use impure solvents and soiled cleaning cloths.
