(1) 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.).
(2) Tolerance for the dimension is MPL-B6xx +0.014, -0.011 mm, (+0.0005, -0.0005 in.); MPL-B8xx +0.016, -0.013 mm, (+0.0006, -0.0005 in.);
MPL-B9xx +0.016, -0.013 mm, (+0.0005, -0.0006 in.).
(3) Tolerance for the dimension is MPL-B6xx +0.43 mm (±0.008 in.); MPL-B8xx and MPL-B9xx +0.52 mm (±0.010 in.).

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
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.
