Motor Load Force Ratings
Motors can operate with a sustained shaft load. The figure shows radial and axial load force
locations, and the tables provide maximum values for each force.
Load Forces on Motor Shaft
The tables represent 20,000 hour L
10
bearing fatigue life at various loads and speeds. The 20,000
hour life does not account for possible application-specific life reduction that can occur due to
bearing grease contamination from external sources.
Loads are measured in pounds; kilograms are mathematical conversions.
Radial Load Force Ratings
