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 InformationHighlights
-
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.
