10.2 Installation/removal of gear units with hollow shafts and keys
Installation SEW-EURODRIVE recommends two variants for installation of gear units with hollow
shaft and key onto the input shaft of the driven machine (= customer shaft):
1. Use the fastening parts supplied for installation.
2. Use the optional installation/removal tool for installation.
1) Supplied
fastening parts
The following fastening parts are supplied as standard:
• Retaining screw with washer (2)
• Circlip (3)
Note the following points concerning the customer shaft:
• The installation length of the customer shaft with contact shoulder (A) must be L8 -
1 mm (0.04 in).
• The installation length of the customer shaft without contact shoulder (B) must equal
L8.
• Always use the supplied NOCO

corrosion and facilitates subsequent removal.
• The keyway dimension X is specified by the customers, but X must > DK.
