What's the Applications of the RJ40 Crossed Roller Bearing?

The RU series crossed roller bearings are widely used in fields with stringent requirements for space and performance, thanks to their high rigidity, precision, and compact design. Specific applications include:

1. Industrial Robots

Joints and Rotating Parts: The integrated inner/outer ring structure with mounting holes makes the RU series easy to install and capable of handling multi-directional loads, making them ideal for critical movement parts like waist joints and rotating arm joints in industrial robots.

Collaborative Robots: The ultra-thin design suits compact collaborative robots, especially at wrist and elbow joints, ensuring precise repeat positioning.

2. Machine Tools and Processing Equipment

CNC Rotary Tables: Used in rotary tables of machining centers, providing stable rotational accuracy and load capacity, supporting operations such as high-precision milling and grinding.

Spindle Systems: Some high-speed machine tool spindles use RU series bearings due to their low friction and high rigidity, enhancing machining efficiency.

3. Medical and Precision Instruments

Medical Imaging Equipment: Devices like CT scanners and MRI machines rely on the high cleanliness and low vibration characteristics of these bearings for accurate imaging.

Optical Instruments: Applied in high-precision measuring instruments and laser cutting equipment, ensuring precise control over minute displacements.

4. Automation and Inspection Equipment

Robotic Arms and Rotary Tables: In automated production lines, they are used in the rotating joints of material handling robotic arms or indexing rotary tables, improving the continuity and reliability of actions.

Semiconductor Manufacturing: Precision rotary platforms in IC packaging equipment and wafer dicing machines require the high rigidity and anti-micro-vibration performance of RU series bearings.

5. Aerospace and Special Fields

Radar and Satellites: RU bearings are utilized in satellite antenna adjustment mechanisms or radar rotating bases, meeting extreme temperature conditions and high reliability requirements.

Drone Gimbals: Lightweight designs cater to the dynamic balance needs of drone camera gimbals.

RU Series (Integrated Inner/Outer Ring Type) Crossed Roller Bearing

The RU series bearings feature provided mounting holes, eliminating the need for a presser flange or housing. Additionally, with an integrated inner/outer ring structure and equipped with washers, their performance is minimally impacted by the mounting procedure. This ensures stable rotation accuracy and torque.

This model supports both inner-ring rotation and outer-ring rotation, offering high flexibility and adaptability.
