Replace Bearings - Siemens SINAMICS G115D Operating Instructions Manual

Additional information on the SIMOGEAR geared motor
12.3 Specific data gearbox
If, following agreement, the gearbox is filled at the factory with special lubricant for the
applications listed 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 deleted 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.

Replace bearings

The bearing service life is finite, greatly depends on the operating conditions and therefore
cannot be calculated reliably. In the operating conditions specified by the operator, bearing life
can be calculated. Changes in vibration and noise pattern are an indication that an immediate
bearing replacement is necessary.
