THK Cross Roller Ring – High-Precision Rotary Bear...

THK Cross Roller Ring – High-Precision Rotary Bearings THK Cross Roller Rings are high-rigidity, high-accuracy bearings designed for smooth rotational motion with minimal friction. They use crossed cylindrical rollers arranged at 90° to each other, allowing them to support radial, axial, and moment loads simultaneously. These rings are widely used in robotics, precision machining, medical devices, and aerospace applications. Types of THK Cross Roller Rings 1. RA Series – Ultra-Thin & Lightweight Compact design with a thin cross-section Suitable for space-constrained applications like robot arms and turntables Provides high rotational accuracy 2. RB Series – High Rigidity & Load Capacity Designed for applications requiring high rigidity and heavy load support Ideal for machine tool rotary tables, industrial robots, and indexing mechanisms Inner and outer rings are separable for easy installation 3. RE Series – Integrated Design for Compact Motion Similar to the RB Series but with an integrated structure for enhanced rigidity Suitable for semiconductor manufacturing, factory automation, and measuring instruments 4. RU Series – Integrated Inner & Outer Ring Non-separable design simplifies installation High rotation accuracy and high load-bearing capacity Commonly used in robot joints, precision rotary tables, and satellite positioning systems Key Features & Benefits of THK Cross Roller Rings ✔ High Rotational Accuracy – The cross-roller design ensures precise motion without play ✔ Compact & Lightweight Design – Ideal for space-saving applications ✔ Simultaneous Load Support – Handles radial, axial, and moment loads for stable operation ✔ Low Friction & Smooth Motion – Reduces wear and improves efficiency ✔ High Rigidity & Stability – Perfect for applications requiring precise and stable rotation ✔ Easy Installation & Maintenance – Available in separable and non-separable types for flexible assembly Applications of THK Cross Roller Rings THK Cross Roller Rings are widely used in industries that require high-precision rotational motion, including: Industrial Robots – Used in robotic arms, rotary joints, and manipulators CNC Rotary Tables & Indexing Mechanisms – Provides high rigidity and precise positioning Semiconductor & Electronics Manufacturing – Ensures smooth motion in wafer processing machines Medical Equipment – Used in MRI scanners, robotic surgery systems, and imaging devices Aerospace & Defense – Essential for satellite positioning, radar systems, and flight simulators Measuring Instruments & Optical Devices – Supports high-precision motion for laser measurement systems and telescopes Why Choose THK Cross Roller Rings?
