Corrosion protection (KS) and surface protection (OS)
for all standard gear units
Features | To 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 stainless steel – Nameplates are made of stainless steel and various motor parts are coated with a finishing varnish – 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. |
