Spur gear pre-stage and three to four (UA115) eccentrics providing highest transmission accuracy, minimum speed ripples and minimum vibration.
The new UA series offers further improved performance data in regards to torque density, positioning accuracy and movement accuracy. It's high efficiency even at low speed and the improved output bearings are to be mentioned in addition to that.
