The units have the feature of small volume, light weight (one third or half volume & weight of general reducer), large transmission ratio range (Ratio of single-stage reducer is from 9 to 87. Ratio of double-stage reducer can reach 7569), high efficiency, high loading capacity and stead & reliable transmission.

The differences between them are the model, higher motor power and the increased permissible torque for X series.
