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.

For motors with a brake, for example MPL-Bxxx-xxx4AA, add to MPL-B6xx dimensions LB, LD. and LE: 108.0 mm (4.25 in.); to MPL-B8xx
dimensions LB, LD. and LE:107.9 mm (4.26 in.); and to MPL-B9xx dimensions LB, LD 127.0 mm (5.0 in.).
