Product Description Extended storage 2.3Extended storage

Design You can also order gear units prepared for "extended storage." SEW-EURODRIVErecommends the "extended storage" type for storage periods longer than 9 months.In this case, a VCI corrosion inhibitor (v olatile c orrosion i nhibitor) is added to the lubri-cant in these gear units. Please note that this VCI corrosion inhibitor is only effective ina temperature range of -25 °C ... +50 °C. The flange contact surfaces and shaft endsare also treated with an anti-corrosion agent. If not specified otherwise in your order, thegear unit will be supplied with OS1 surface protection. You can order OS2, OS3 or OS4 instead of OS1.

Surface protection Suitable forOS1 Low environmental impact OS2 Medium environmental impact OS3 High environmental impact OS4 Very high environmental impact

The gear units must remain tightly sealed until taken into operation to prevent the VCIcorrosion protection agent from evaporating.Gear units will be supplied with an oil fill according to the mounting position (M1 ... M6)and are ready for operation. Check the oil level before you start operating the gear unitfor the first time! Storage conditions Observe the storage conditions specified in the following table for extended storage:

Packed in containers, with desiccant and moisture indi-cator sealed in the plastic wrap.Under roof, protected against rain and snow, no shock loads.Up to three years with regular checks of the packaging and moisture indicator (rel. humidity < 50 %).OpenUnder roof, enclosed at constant temperature and atmospheric humidity (5°C< Climate zone packaging
