SX Crossed Roller Bearing

Crossed Roller Bearings feature cylindrical rollers arranged alternately at right angles between the inner and outer rings. This design allows the bearing to support radial loads, axial loads in both directions, and moment loads simultaneously within a compact structure.

With high rigidity, smooth rotation, and excellent positioning accuracy, Crossed Roller Bearings are ideal for applications requiring precise motion control and space-saving designs. They are widely used in industrial robots, machine tools, precision rotary tables, and automation equipment.

• SX Type is an ultra-thin crossed roller bearing with an integrated inner ring and a split outer ring. With the same shaft diameter, the SX has a smaller cross-sectional size compared to the RB type. Due to its ultra-thin design, both inner and outer rings have no mounting holes, requiring flanges and bearing housings for installation. SX bearings are ideal for applications where the inner ring rotates.

Key Advantages

• Ultra-Thin and Compact Design:
  The SX type has a smaller cross-sectional size compared to RB type with the same shaft diameter, ideal for applications requiring lightweight and space-saving solutions.

• Integrated Inner Ring and Split Outer Ring:
  Ensures stable inner ring rotation, maintaining precision and rigidity even in compact configurations.

• High Rotational Accuracy:
  The inner ring rotates smoothly with minimal deflection, suitable for precision machinery and robotic joints.

• Stable Torque Performance:
  The one-piece inner ring combined with cross-arranged rollers ensures consistent torque during operation.

• Flexible Installation:
  Both inner and outer rings have no mounting holes; flanges and bearing housings are required, allowing secure installation while preserving bearing performance.

• Ideal for Rotating Inner Ring Applications:
  Specifically designed for scenarios where the inner ring rotates, providing high precision in constrained spaces.

OEM / Customization

This bearing supports OEM services and customization, allowing customers to specify brand labeling, lubrication options, precision tolerances, or packaging according to their requirements. It can be tailored to meet unique operational needs, ensuring optimal performance and full compatibility with customer-specific equipment.
