Features
Easy to install Fewer mounting components Reduced weight
Since the Model RF is lightweight, it is also suitable for applications such as ceiling-mounted rotating arms. Additionally, it is capable of smooth rotary motion because it can receive loads and moments in any direction.
Thin, Lightweight, Flanged Design
The unique flanged design achieves an even lighter weight.

Reduced Weight and Number of Robot Components
This is the ideal product for robots requiring weight reduction and improved productivity.
・Can be installed directly onto a shaft or housing | → | Increases a robot’s productivity |
・ Does not require a presser flange | → | Simplifies design and reduces installation time |
・ Reduces product weight | → | Allows lighter weights than conventional products |
Structure and Lineup
Structure
The cross array of rollers allows a single bearing to receive loads and moments in all directions. The flanged design simplifies installation and minimizes the cross-sectional area of the product. This is a lightweight unit that maintains the ease of assembly achieved by the Model RU, a conventional cross roller ring with mounting holes.
Lineup
Straight-Type Inner Ring
Allows for high levels of freedom in design and provides space for wiring, etc.
■ Same inner ring dimensions as the Model RA
Can easily replace existing equipment.
