Since the mounting holes have already been machined for this series of products, there is no need for additional fixing flanges or support housings. Moreover, the company adopts an integrated inner and outer ring structure with a built-in housing, so installation has almost no direct impact on performance. As a result, stable rotational accuracy and torque can be achieved. The bearing can be used for both outer ring rotation and inner ring rotation.
Main Features of the RU Series Bearings:
·Integrated Structure: Both the inner and outer rings are of a one-piece design, enhancing overall bearing rigidity.
·Simplified Installation: Mounting holes are provided on both the outer and inner rings, eliminating the need for fixing flanges and support seats, which greatly simplifies the installation process.
·High Precision and High Rigidity: The integrated structure ensures stable rotational accuracy and rigidity, with installation having minimal influence on bearing performance.
·Applicable Applications: Especially suitable for applications where both the inner ring and the outer ring are required to rotate.
