Note
These recommendations are not a guarantee of the lubricant quality provided by your
supplier. All lubricant manufacturers are responsible for the quality of their own products.
The oil viscosity is decisive for the oil selection (ISO VG class). The viscosity is specified on
the rating plate of the gearbox. The viscosity class indicated applies for the contractually
agreed operating conditions.
In the case of different operating conditions, please contact Technical Support.
If, following agreement, the gearbox is filled at the factory with special lubricant for the
special applications referred to above, the lubricant is shown on the rating plate.
The oil quality must meet the gearbox lubricant requirements specified in the NT 7300 table.
The Siemens warranty is otherwise null and void. We recommend the use of one of these
gearbox lubricants
.
These gearbox oils are subject to constant testing and meet the specified
requirements. It is possible that the recommended oils are removed or replaced by oils that
have been further developed at a later point in time. We recommend that you regularly check
as to whether the selected lubricating oil is still recommended by Siemens. Otherwise
change the product.
8.3 Replace bearings
The bearing service life depends greatly on the operating conditions and so cannot be
calculated reliably. In the operating conditions specified by the operator, bearing life can be
calculated and indicated on the rating plate. If no information is given, changes in vibration
and noise pattern can serve as an indicator that an immediate bearing replacement is
necessary.
