Table 3-4 Roller Bearing Versions; Table 3-5 Minimum Radial Forces - Siemens SIMOTICS M-1PH8 Operating Instructions & Installation Instructions

Description
Supplementary devices
A KTY 84 temperature sensor is installed (Page 71) in the stator winding for winding control.
Depending on the order options, various supplementary devices such as encoder systems can
be installed or mounted, which are suitable for use in Zone 22.
Ambient conditions
The standard machines are not suitable for use in corrosive atmospheres, atmospheres with
a high salt content, or outdoor applications.
Roller bearings
The machines are equipped with different types of roller bearings depending on the version
and the operating conditions described in the order. If the machine is equipped with a
regreasing system, you will find the relevant data on the machine's lubricant plate.
The following standard roller bearing versions are available:
