Hollow Rotary Actuator - NT Series
Product Description
- Direct attachment with simple and reliable design.
- Large hollow rotary table for concise wiring and piping.
- Accurate and fast positioning. Able to quickly position inertial load.
- Repeat origin returns easily. Save you the trouble of designing and perchance new parts.
- Servomotor gearbox.
Feature
- Max Backlash of 30 arc-seconds.
- Large hollow rotary flange with a hollow bore for wiring or shafts.
- Hollow bore driven by your servo motor via a large helical ring gear integrated into a rotating flange. Provides smooth, accurate and fast positioning and indexing with high positional accuracy, rigidity and heavy axial load capacity.
- Flange rotates on a precision, high-capacity crossed-roller bearing.
- Larger reduction ratios are achievable by inputting through a planetary or right-angle gearhead.
- Standard crossed-roller bearings - reliable quality you can trust.
