High Precision & High rigidity, Reduction gear RV Original series

Bearingless Model

Nabtesco's precision reduction gear is a reduction gear for precise motion control which uses a planocentric reduction gear mechanism. This reduction gear design has advantages in rigidity and resistace against overload with a compact body due to a large number of simultaneously engaged gear teeth. Furthermore, minimal backlash, rotational vibration and low inerita lead to rapid acceleration, smooth
motion and accurate positioning.

Features :
- No support bearing
