12 N-Series Motor Installation Instructions
Publication 1398-IN519A-EN-P — March 2001
The following table represents load factors that provide a 20,000-hour L10
bearing fatigue life for N-Series motors. These load factors do not account
for possible application-specific life reduction factors that may occur, such
as bearing grease contamination from external sources.
With no radial load, the axial load rating is 100% of the radial load rating
from the table below. With a radial and an axial load, the axial load rating
is 44% of the radial load rating from the table below.
