2.4 Permissible load for the shaft
POINT
Do not use a rigid coupling as it may apply excessive bending load to the
shaft, leading to shaft breakage.
(1) Use a flexible coupling and make sure that the misalignment of the shaft is less than the permissible
radial load.
(2) When using a pulley, sprocket or timing belt, select a diameter that will fit into the permissible radial
load.
(3) Excess of the permissible load can cause the bearing life to reduce and the shaft to break.
(4) The load indicated in this section is static load in a single direction and does not include eccentric load.
Make eccentric load as small as possible. Not doing so can cause the servo motor to be damaged.
