Feature and application of RAU7008C Bearing

RAU7008CC0 is a crossed roller bearing. The following is an introduction to its features and applications:

Features

High Precision: The rollers of cross roller bearing are arranged in a crossed pattern, which can prevent the rollers from tipping over or rubbing against each other. This can prevent the increase of rotational torque. Even when preloaded, stable and high-precision rotational motion can be obtained.

High Rigidity: Compared with traditional models, the rigidity is increased by 3 to 4 times. The rollers are arranged vertically and crosswise, enabling a single bearing to withstand loads in all directions, such as radial loads, axial loads, and moment loads.

Compact Design: It belongs to the RA series and is a compact type that reduces the thickness of the inner and outer rings of the RB type cross roller bearing to the limit. The structure is a split outer ring structure, which has the characteristics of light weight and compact design.

Easy to Operate: The divided inner ring or outer ring, after loading the rollers and the spacer retainer, is fixed together with the cross roller bearing ring to prevent separation from each other. The installation operation is very simple.

Applications

Industrial Robots: It is suitable for the joint parts and rotating parts of industrial robots, such as the rotating connection points of robot arms. Its high precision can ensure the accuracy and repeatability of the robot's movement, the high rigidity can withstand various forces and torques generated during the robot's movement, and the compact design helps to reduce the weight and volume of the robot, improving the flexibility and motion performance of the robot.

Machining Centers: It can be applied to the rotary tables of machining centers. The high-precision rotational motion can ensure the machining accuracy, and the high rigidity can withstand various loads when the table rotates and carries workpieces, making the machining process more stable and conducive to improving the machining quality and efficiency.

Medical Instruments: For example, the rotating parts in medical imaging equipment, the joint parts of surgical instruments, etc. High precision can ensure the accuracy and stability of the instrument during operation, providing reliable support for medical diagnosis and treatment; its compact design and good rotational performance also help medical instruments achieve miniaturization and fine operation.

Measuring Instruments: It is used in various measuring equipment that requires high-precision measurement and rotational motion, such as the rotary tables and dividing heads of measuring instruments. It can ensure the accuracy and stability of the measurement process, reduce errors, and improve the measurement accuracy and reliability.

IC Manufacturing Equipment: It is applied to the rotating parts of semiconductor manufacturing equipment, such as lithography machines and wafer handling equipment. High precision and high rigidity can meet the strict requirements for precision and stability during the manufacturing process of the equipment, helping to improve the yield rate and production efficiency of chip manufacturing.
