Load Force Ratings
The following section contains the 230V and 460V MP-Series radial and axial motor load force ratings.
MP-Series motors are capable of operating with the maximum radial or maximum axial shaft loads listed in
the following tables. Radial loads listed are applied in the middle of the shaft extension. The tables below
represent an L10 bearing fatigue life of 20,000 hours. This 20,000-hour life does not account for possible
application-specific life reduction that may occur due to bearing grease contamination from external
sources.
