Assembly/disassembly kit by SEW

EURODRIVE
INFORMATION
The depicted assembly kit for attaching the customer shaft is a recommendation by
SEW
‑
EURODRIVE.
• You must always check whether this design can compensate the present axial
loads.
• In particular applications (e.g. mounting agitator shafts), a different design may
have to be used to secure the shaft axially. You can use your own devices to se-
cure the shaft axially, if you ensure that these designs do not cause potential sour-
ces of combustion according to DIN EN 13463 (e.g. impact sparks).
The following figure shows the SEW
