Regreasing Intervals - Siemens SINAMICS S 1PH7 Configuration Manual

Regreasing
For motors which can be re-lubricated at defined re-lubricating intervals, the bearing lifetime
can be extended and/or unfavorable factors such as mounting conditions, speed, bearing
size and mechanical load can be compensated (refer to the table "Recommended bearing
change intervals (standard bearing design)").
Depending on the frame size, restrictions have to be taken into account - e.g. vertical
mounting/shaft position.
It is possible to regrease motors, shaft heights 180 and 225. A lubricating nipple is optionally
provided, Code K40.

Regreasing intervals

Regreasing intervals are specified:
● on the lubrication plate of the induction motor
● in the table "Re-lubrication intervals"
The values specified in the following table are valid for the following conditions:
● Cooling medium temperature up to max. +40
● Horizontal mounting position
● Average operating speed, refer to the table "Recommended bearing change intervals
● Complying with the permissible radial and axial forces (refer to Chapter "Radial and axial
● Complying with the maximum permissible speeds (refer to Chapter "Technical data and
1PH7 induction motors (Machine tools)

NOTICE
For longer periods of time (e.g. longer than 1 re-lubrication interval) between shipping
and commissioning the motor, the bearings must be lubricated. When re-lubricating, the
shaft must be rotated in order to distribute the grease around the bearings (for additional
information, see the Operating Instructions).
