CRBH Series Crossed Roller Bearing Compact Ultra Thin Single Row Bearing

CRBH 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.

• CRBH Type is an ultra-thin crossed roller bearing with integrated inner and outer rings. Due to its ultra-thin design and absence of mounting holes, installation requires flanges and supporting housings. The one-piece structure of both rings ensures that mounting has minimal influence on performance, providing stable rotational accuracy and consistent torque. RBH bearings are ideal for applications where both inner and outer rings rotate, but compact dimensions are required.

Key Advantages

• Ultra-Thin and Compact Design:
  Retains the ultra-thin profile of the RBH type, minimizing thickness while maintaining high rigidity, ideal for space-constrained applications.

• Integrated Inner and Outer Rings:
  One-piece construction ensures stable performance; mounting does not compromise rotational accuracy or torque.

• Enhanced Load Capacity and Rigidity:
  Optimized internal design and material selection allow CRBH bearings to handle higher radial, axial, and moment loads compared to standard RBH.

• High Rotational Precision:
  Maintains precise rotational motion under preload, making it suitable for high-precision applications such as robotic joints, compact actuators, and precision machinery.

• Reliable Torque Performance:
  Uniform torque and smooth rotation are maintained even in compact configurations, ensuring stability in sensitive motion systems.

• Customizable Options:
  Can be tailored for specific load, size, or precision requirements, providing flexibility for specialized engineering applications.

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.
