What's the Applications of the RU124 Crossed Roller Bearing?

The RU124 cross roller bearing, with its high precision, high load-carrying capacity, and compact design, is widely used in the following fields:

1. Machine Tool Industry

• Mainly used in rotary tables and rotating components of high-precision CNC machines, grinding machines, lathes, and other equipment. Its high rigidity and ability to withstand combined loads meet the demands of precision machining.

2. Industrial Robotics

• As a core component of joints or rotating parts, the RU124 bearing’s compact structure and high-speed characteristics (up to 480 rpm) make it suitable for high-speed motion and frequent start-stop scenarios in robotics.

3. Aerospace

• Used in precision rotating devices such as satellite antennas and radar systems. Its high rigidity and shock resistance are capable of handling complex environments.

4. Medical Equipment

• Examples include surgical robots and rotating platforms in imaging equipment, where high precision and low friction are required. The RU124 bearing meets the stability requirements of medical applications.

5. Precision Instruments and Automation Equipment

• Includes IC manufacturing equipment, measuring instruments, and CNC rotary tables. Its rotational accuracy (up to P5/P4 grade) and miniaturized design are ideal for precision operations.

6. Medical Devices

• Such as rotating components in MRI machines and CT scanners, which require high rigidity and low noise. The RU124 bearing provides stable support.

7. Energy and Heavy Machinery

• Used in heavy-load scenarios such as wind turbine yaw systems and oil drilling equipment. Its radial load capacity (Cr: 33.1 kN) and axial load capacity (Cor: 50.9 kN) can handle high-load demands.

8. Semiconductor Manufacturing

• For example, rotating worktables in wafer processing equipment, which require high cleanliness and long-term stable operation. The RU124 bearing’s sealed design and low-friction characteristics meet these requirements.

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.
