Load Force Ratings
The following section contains the N-Series motor radial load force ratings and shaft load force ratings.
Motors are capable of carrying an axial load in most applications according to the following general
guidelines. These guidelines should only be used as approximations.

• With no radial load, the axial load rating is 100% of
the radial load rating from the table above.
• With a radial and an axial load, the axial load
rating is 44% of the radial load rating from the
table above.
