Circular Arc Ring Unit RGU series

The RGU Series has a circular arc ring model lineup.

Available in all sizes and angles, contributing to space-saving, simplified layout, and cost reduction.

Depending on the combination, it is also possible to use hollow diameters and sizes larger than full rings.

Technical Information
Circular Arc Ring Unit RGU series

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.

Highly Flexible Angle and Size Settings

Its swivel shaft bearing uses an R Guide. Set the required angle size according to your needs.

Easy-to-mount motor

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