Reinforced bearings
Motors of the 1PS0, 1PS1 1PS5 and 1MD5 type series can
be designed with cylindrical roller bearings at DE for higher
cantilever forces, e.g. for belt drives. For frame size 160 and
above, the motors are equipped with a relubrication device
at DE and NDE.
Selection of roller bearings
For SIMOTICS XP motors, the version with cylindrical roller
bearings at DE and relubrication device at DE and NDE is an
alternative to the standard version.
The located bearing is at NDE. A relubrication device for
DE and NDE is standard.
