THK RU445 Precision Crossed Roller Bearing 350x540x45mm for Heavy Robotics & CNC

The RU445 Crossed Roller Bearing is an ultra-precision, large-scale rotary solution designed for heavy-duty industrial automation. Featuring integrated inner and outer rings with pre-drilled mounting holes, it eliminates the need for complex press-fit housings. This model is the premier choice for large-bore CNC rotary tables, industrial robot bases, and medical imaging gantries.

• Integrated Design: Mounting holes on both rings allow for fast, bolt-on installation.

• Extreme Load Capacity: Engineered to handle massive 473 kN static loads.

• Exceptional Rigidity: Crossed-roller geometry provides superior tilting moment resistance.

• Large Bore Size: 350mm ID supports large-scale spindle and cable management.

• Precision Performance: Available in P2/P4 grades for sub-micron rotational accuracy.

• Heavy Industrial Robotics: Main swiveling bases and high-payload joints for large robots.

• Large CNC Machinery: Heavy-duty 4th/5th axis rotary tables and large vertical boring mills.

• Medical Technology: Large-bore CT scanners and MRI gantries.

• Aerospace: High-torque radar pedestals and large satellite tracking systems.

• Industrial-Grade Quality: Designed for demanding heavy-load environments.
• Reliable Delivery: Efficient production and global logistics support.
• Technical Expertise: Professional guidance for selection and system integration.
• Customization Available: OEM/ODM solutions tailored to your project needs.
