The RU445X Crossed Roller Bearing is a high-precision, heavy-duty rotary solution featuring an integrated ring design. The "X" configuration signifies a specialized tapped-hole arrangement on the inner ring, allowing for direct mounting without additional pressure plates. It is specifically designed for large-scale industrial robot bases, backlash-free CNC rotary tables, and medical gantries.
X-Type Mounting: Tapped holes on the inner ring simplify assembly and increase structural rigidity.
Extreme Load Capacity: Built to support static loads up to 473 kN in high-stress environments.
Enhanced Tilting Resistance: Crossed-roller geometry provides superior stability against moment loads.
Large Bore Diameter: 350mm inner diameter allows for easy passage of large spindles and wiring.
Sub-Micron Accuracy: High-precision P2/P4 standards ensure zero-play, high-torque rotation.

1. What is the benefit of the "Slewing" design in the RU445X?
The slewing design allows a single bearing to replace a multi-bearing setup. It handles radial, axial, and moment loads simultaneously, saving space and reducing weight in large machinery.
2. Is the RU445X suitable for both inner and outer ring rotation?
Yes. Since both rings are integrated units, the RU445X maintains high rotational accuracy and rigidity regardless of which ring is driven.
3. Can GQZ provide custom lubrication for extreme environments?
Absolutely. We offer specialized grease for high-speed, high-temperature, or vacuum-sealed environments to match your specific application requirements.
