Tolerances and Supplemental Dimensions
Motor Load Force Ratings
Motors are capable of operating with a sustained shaft load. The location of the radial and axial
load force is shown in the figure, and maximum values are listed.
Loads are measured in pounds, kilograms are mathematical conversions.
Load Forces on Shaft
The following tables represent 20,000 hour L

bearing fatigue life at various loads and speeds.
This 20,000 hour life does not account for possible application-specific life reduction that can
occur due to bearing grease contamination from external sources.
