  • 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

    Able 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
