NABTESCO – Positioner
Positioner Unit
Positioners units that use the Precision Reduction Gear RV. Support for all major servo motors. Drastically reduces the time and effort required for design, manufacturing and assembly,
RVP-A
2-axis positioner unit
Basic InfoAble to install motors from all major servo motor manufacturers, making collaborative work with many different robots possible. Multiple reduction ratios mean the customer can choose the best possible combination for their application, reducing cycle times or allowing for use of small motors.
- Able to choose from multiple reductions ratios
- Support for all major servo manufacturers
- Addition parts such as covers and stoppers are available
- Completely sealed and filled with grease
- High speed, high accuracy positioning

Variable tilt angle turntable unit
Basic InfoA human centered design improves the workability, reducing the burden on workers and the time required for setting the part, and also improving mixed model production. Also, areas previously unreachable by robots can now be accessed by tilting the table and varying the height
- Support for all major servo manufacturers
- A wide variety of options are available
- Completely sealed and filled with grease
- The table can be tilted
