Introduction:
Our Internal Gear Crossed Roller Bearings integrate a high-precision gear on the bore (inner ring), creating an exceptionally compact and space-saving unit. This design combines the superior load capacity and rigidity of the crossed roller design with the convenience of an internal drive mechanism, ideal for applications where a pinion can be mounted inside the bearing diameter for a streamlined and robust power transmission system.

Key Advantages:

• Ultimate Space Optimization: The internal gear design allows the driving pinion to be nestled within the bearing’s footprint, significantly reducing the overall system envelope and enabling more compact machinery design.

• Exceptional Rigidity & Accuracy: The 90° crossed roller arrangement provides high moment rigidity and precise rotational stability by simultaneously supporting radial, axial, and moment loads.

• Integrated & Simplified Design: Combines a bearing and an internal gear into one ready-to-install unit, reducing part count, simplifying assembly, and enhancing structural integrity.

• Smooth & Efficient Operation: Offers low friction and high rotational accuracy for reliable, quiet performance in precision applications.

• High Torque Transmission: The internal gear mesh allows for efficient and robust torque transmission directly at the point of rotation.

Primary Applications:

• Robotics: Ideal for compact robot joints, especially in articulated arms and wrists where space is at a premium.

• Machine Tools: Used in rotary tables, indexing heads, and swivel bases where a compact, integrated drive is required.

• Automation & Rotary Stages: Perfect for precision indexing and positioning stages in automated equipment.

• Medical & Semiconductor Equipment: Suitable for compact rotating modules in imaging systems and wafer handling tools.

• Defense & Aerospace: Applied in radar platforms and targeting systems where a low-profile, high-stiffness solution is critical.
