📌 What is a Crossed Roller Bearing?
A Crossed Roller Bearing is a compact bearing that uses cylindrical rollers arranged orthogonally (at 90° angles) in a single raceway groove. This unique structure enables it to support loads from all directions — radial, axial, and moment — with outstanding rigidity and accuracy.

📌 Functions and Benefits of Crossed Roller Bearings
✅ Multi-Directional Load Support – Handles radial, axial, and moment loads with one bearing
✅ Ultra-High Rigidity – Ideal for applications requiring zero vibration and micro-movement control
✅ Compact Design – Reduces installation space and weight
✅ Stable Rotational Accuracy – Suitable for high-precision rotation over long periods
✅ Long Life with Smooth Motion – Uniform roller contact reduces wear and increases lifespan

📌 Structural Types
🔹 Integrated Type (V Series) – Inner and outer rings are one piece; offers high rigidity and easy installation
🔹 Split Type (Standard Type) – Outer ring split and secured by screws for easier assembly
🔹 Open or Sealed – Sealed versions use synthetic rubber for cleanroom or dust-prone environments
🔹 Stainless Steel Options – Ideal for corrosion-sensitive or cleanroom use

＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝

📌 Applications of Crossed Roller Bearings
🔹 Industrial Robots – In joints or rotating arms for precision control
🔹 Machine Tools – For indexing tables or spindles requiring accurate rotation
🔹 Medical Devices – In imaging equipment and surgical systems
🔹 Inspection Equipment – To maintain precision in positioning and angle detection
🔹 Semiconductor Manufacturing – Where micro-scale precision is critical
