THK RAU and RAUV Series Cross Roller Ring
The THK RAU Series is built with an extremely small cross-sectional area, making it a strong choice for lightweight, compact devices. Its integrated inner and outer ring structure lets it handle both inner ring and outer ring rotation. It comes in two lineups: a small-diameter, 5mm thin type with a basic dynamic load rating from 1.12 kN to 3.37 kN, and an RA-interchangeable type rated from 5.10 kN to 25.8 kN, so it can swap into existing RA Series setups. Model RAUV is the full roller version, rated from 7.24 kN to 41 kN, offering higher rigidity for low speed rotary use under heavier loads.
This series suits small robotic joints, compact rotary tables, and other space limited applications where every millimetre of cross section counts.
