Use of the single-stage DA gearboxes results in significant cost advantages compared to available two-stage gearboxes of the identical torque class
Important factor when people are working near the drive applications, as for example in the medical field.
Connection geometry does not require a complex installation, nor does it require an adjustment of the drive shaft
Connection of several motor shaft diameters is possible, allowing the use of motors from many different manufacturers
