Corrosion and surface protection
Product Description
Surface
protection OS
Instead of the standard surface protection, the motors and gear units are available with
surface protection OS1 to OS4 as an option. The special procedure Z can also be per-
formed in addition. The special procedure Z means that large surface recesses are
sprayed with a rubber filling prior to painting.

NOCO
®
fluid As standard, SEW-EURODRIVE supplies NOCO
®
fluid corrosion protection and
lubricant with every hollow shaft gear unit. Use NOCO
®
fluid when installing hollow shaft
gear units. Using this fluid helps prevent contact corrosion and makes it easier to
assemble the drive at a later date.
NOCO
®
fluid is also suitable for protecting machined metal surfaces that do not have
corrosion protection, including parts of shaft ends or flanges. You can also order larger
quantities of NOCO
®
fluid from SEW-EURODRIVE.
NOCO
®
fluid is food grade according to NSF certified H1.
