Precision
Fine Cyclo UA-Series
Double stage high precision high torque density gearbox
Overview
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.
- Less than 0.5 arcmin Lost Motion
- Ideal for applications with traverse movements
- Highest Torque density available on the market
- Highest overall available Torque
- High input and output speeds possible
- Additional ratios available on request
Variants:
- Basic design to be fully integrated in robotic arms
- Fully sealed version including motor flange available
