Full Ring Unit RGU series

A Zero-Backlash reducer with high rigidity and large hollow diameter.

Integrates a cam ring, roller pinion, and a Ball Reducer as a single unit, reducing design complexity and assembly man-hours.

Technical Information
Full Ring Unit

Highlights

Unitization

Unitization of TCG Cam Ring and Ball Reducer has reduced the man-hours required for designing and assembling.

Zero-Backlash and high precision

Zero-Backlash has realized high-precision positioning.

Large-caliber hollow hole

The large-caliber through, hollow hole can pass wiring and piping through there to make the entire unit neat and ordered.

Low noise and low vibration

All contacts of the drive unit by means of rolling has eliminated gear rattle and reduced vibration.

High load and high rigidity

Cross-roller bearing employed for the slewing shaft can adequately receive external force acting on the table.

Easy-to-mount motor

Motor mounting is easy with the availability of various attachments applicable to standard servo motors of various manufacturers.
