Motor Load Force Ratings
Motors are capable of operating with a sustained shaft load. The load force
locations are shown in the figure and maximum values are in the tables.
Loads are measured in kilograms; pounds 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.
