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.

1. Does the RU445 support both inner and outer ring rotation?
Yes. Since both rings are integrated (not split), the RU445 provides high rotational accuracy regardless of which ring is the rotating element.
2. What is the difference between RU445 and RU445X?
The RU445X typically indicates the inner ring has tapped holes (X-type), while the standard RU445 uses through-holes. This allows for more flexible mounting options depending on your equipment design.
3. Is this bearing pre-lubricated for immediate use?
Yes. All GQZ RU445 bearings are pre-lubricated with high-quality lithium soap-based grease. We can also provide vacuum-compatible or high-temperature grease upon request.
