The Nabtesco Actuator is a sealed and prelubricated precision gearbox with servomotor in a compact design. The AF series is a compact actuator directly amounted servomotor, which is succeeded to features of Precision Reduction Gear RV, "High accuracy", "High rigidity"and "High reliablity".


The Nabtesco Gearhead is a sealed and prelubricated precision gearbox, complete with accommodations for motor mounting ( major motor manufacturers). Three input types are available.

The precision reduction gearhead series features an easy to use design utilizing fittings compatible with all major servomotors and sealed with grease before shipping, the new series has also reduced the total length by up to 15%.

The RD2 series introduces the right angle type as a new input option. The right angle input allows for the creation of lower profile designs to be set up in smaller spaces. Especially useful for turn table applications, the right angle input type maintains high accuracy positioning while allowing for space saving, low profile designs.
