RB Precision Cross Roller Bearing

Bearing Features:
1. High Precision: Precision can reach P4 and P2 grades;
2. High Rigidity: This series of bearings all have preload;
3. High Load Capacity: Can withstand axial loads, radial loads, and overturning loads;
4. Compact Size: The bearing's small size saves space in the host machine.

Advantages of RB Precision Crossed Roller Bearings Compared to Traditional Bearings:
1. Structural Aspects: The structure of RB precision crossed roller bearings is much simpler than that of traditional bearings. Through multiple rows of cylindrical rolling elements, considerable axial and radial load-bearing capacity and overturning moment can be achieved, resulting in a much simpler structure.
Traditional bearings require multiple sets arranged sequentially to achieve the same effect, which greatly simplifies design and assembly. The three-row roller combination slewing bearing structure and the single-row raceway structure of crossed roller bearings require significantly less space and are much easier to assemble compared to traditional bearings.
2. Installation: The RU, XU, and XSU series crossed roller bearings also feature mounting holes, achieving comparable installation and performance.
3. Maintenance: Crossed roller bearings are designed with lubrication holes and grooves, facilitating lubrication. They use aviation-grade grease, reducing the need for frequent grease changes and ensuring bearing stability and lifespan.

Applications:
RB type bearings are widely used in machine tools, industrial machinery, robots, and automation equipment. They can withstand high-speed rotation and complex loads while maintaining high precision and rigidity. Therefore, RB type bearings are particularly suitable for equipment requiring high-precision positioning and stability, such as worktables and articulated mechanisms.
