RU with installation hole type
RU21040X
Integral inner and outer rings with mounting holes. Since both rings feature mounting holes, no fixing flanges or support seats are required during installation. Furthermore, as both rings are of an integral structure, installation has virtually no impact on performance, ensuring stable rotational accuracy and torque. Suitable for applications where either the inner or outer ring rotates. To meet the miniaturization demands of industries such as humanoid robotics, ultra-compact and ultra-thin RU-type products have been developed, with bore diameters as small as 8mm and thicknesses down to 5mm.
