Features
To optimally protect motors and gear units that are subject to severe environmental influences,
SEW-EURODRIVE offers possibilities to increase the resistance of highly stressed surfaces.
KS corrosion protection
Measures to increase the resistance to corrosion:
–
All retaining screws that are loosened during inspection or maintenance work are made of stain-
less steel
–
Nameplates are made of stainless steel and various motor parts are coated with a finishing var-
nish
–
The flange contact surfaces and shaft ends are treated with a temporary rust preventive
–
In addition, clamping straps are used for brakemotors
OS surface protection
In addition to the standard surface protection, motors and gear units are optionally available with
surface protection OS1, OS2, OS3 or OS4. This makes the gearmotors well equipped for operation
under various ambient conditions.
