, length in mm of the shaft end on FKM9 servomotors. See dimension
according to model in the dimensions drawing.
Note
. When applying a combined axis and radial load, decrease the
maximum radial force allowed “Fr” to 70 % of the value indicated in the
table.

WARNING.
Avoid hitting the servomotor and especially its shaft when installing
transmission pulleys or gear boxes. These servomotors have extremely
fragile optical and electronic components.
Use some tool that is supported in
the threaded hole on the shaft to
insert the pulley or the gear!
