Extended storage
Product Description
2.4 Extended storage
Type You can also order the gear units prepared for "extended storage". SEW-EURODRIVE
recommends the "extended storage" type for storage periods longer than 9 months.
In this case, a VCI (v
olatile corrosion inhibitor) is added to the lubricant in these gear
units. Please note that this VCI corrosion inhibitor is only effective in a temperature
range of -25 °C...+50 °C. The flange contact surfaces and shaft ends are also treated
with an anti-corrosion agent. If not specified otherwise in your order, the gear unit will be
supplied with OS1 surface protection. You can order OS2, OS3 or OS4 instead of OS1.
Storage
conditions
For extended storage, observe the storage conditions specified in the following table:
The gear units must remain tightly sealed until taken into operation to prevent the VCI
corrosion 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 unit
for the first time!
