Article: 00090416

Rotary positioning stage / precision / compact

The RA Series is a zero-backlash reducer designed for small to medium-size FA applications. It delivers high accuracy, rigidity, and speed.
The RA is suitable for equipment that demand motions with a high level of accuracy and speed.Zero Backlash
The RollerDrive uses a unique preload mechanism to completely eliminate backlash and deliver output motions that are faithfully true to input commands.
Positioning accuracy is particularly good with direction reversing motions.
Highest Level of Accuracy in the RollerDrive Series
Delivers good positioning accuracy and runout accuracy, which are otherwise difficult qualities to attain with a small reducer.
High Rigidity
The output shaft is a solid-piece cross roller bearing designed for durability against axial and radial loads.
High Speed
Max output speed 150 rpm (200 rpm for the RA40)
Choice of Motors
Dedicated fittings are available for mounting motors from various manufacturers.
High Efficiency, Direct Drive
Motor couples directly to the input shaft for a direct transfer of power with less transfer loss.
