Output coupling

NOTICE
Motor damage caused by rotating forces
Output couplings, especially stiff metal bellows-type couplings can exercise rotating forces
on the shaft. These forces can result in bearing motion and in turn damage the motor.
• Rotating forces are not permissible.
To achieve optimum output characteristics, we recommend ROTEX
KTR company.
The advantages of ROTEX
● 2 to 4x torsional stiffness of a belt gearbox
● No teeth meshing (when compared to a belt gearbox)
● Low moment of inertia
● Good closed-loop control response
KTR can provide support when selecting the coupling, see http://www.ktr.com
