RU445G High-Precision Crossed Roller Slewing Bearing 350x540x45mm for Industrial Robot Base

The RU445G Crossed Roller Bearing is a heavy-duty, integrated-ring rotary solution designed for maximum structural stability. The "G" configuration features through-holes on both the inner and outer rings, allowing for flexible mounting using standard bolts. With its massive 350mm bore and 540mm outer diameter, the RU445G is the industry standard for large-scale CNC rotary tables, heavy-payload robot bases, and high-torque medical gantries.

• Dual Through-Hole Design: Integrated holes on both rings simplify through-bolt mounting for maximum security.

• Extreme Static Load: Engineered to support up to 473 kN, making it ideal for heavy industrial machinery.

• High Tilting Moment Rigidity: Crossed-roller geometry provides 3x the stiffness of traditional ball bearings.

• Integrated Ring Structure: Single-piece construction ensures superior rotational accuracy and higher speeds.

• Backlash-Free Performance: Factory-set preload options deliver smooth, play-free motion for precision tasks.

• Heavy Industrial Robotics: Base rotation for high-payload robotic arms and swiveling pedestals.

• Large-Scale CNC Machinery: Heavy-duty 4th/5th axis rotary tables and milling machine worktables.

• Medical Technology: Precision rotation for large-bore CT and MRI imaging systems.

• Precision Radar & Satellites: High-torque antenna pedestals and deep-space tracking mounts.
