2.6 Torque Restraint

Shaft-mounted geared motors require a suitable torque restraint to resist the reaction torque. Torque arm with mounting
sets are available as an option (see 6.7.1 Torque Arm Set). It is always important to ensure that the torque arm does not
create excessive constraining forces due to the driven shaft running untrue, for example. Excessive backlash can result in
excessive shock torques in switching or reversing operations.
