Comparison with Similar Types:
- Compared to XSU080318 & XSU080258: Larger capacity and stiffness, suitable for heavy-duty machinery rather than compact robotic units.
- Compared to XSU140544: Offers a broader inner diameter and higher rigidity, ideal for systems needing larger rotational platforms.
- Compared to XSU140744: Slightly smaller size but better balance between space-saving design and structural stiffness.
- Unique Advantage: The XSU140644 is engineered as a mid-to-large scale solution, offering versatility in applications that require both compact installation and high rigidity without oversizing the system.

Frequently Asked Questions (FAQ)
Can the XSU140644 handle combined loads?
Yes. Its crossed roller structure allows it to support axial, radial, and tilting moment loads simultaneously, ensuring smooth and stable performance under complex force conditions.
Is the XSU140644 preloaded?
The bearing is factory-preloaded, which means it provides consistent rotational accuracy without the need for additional adjustment. Preloading also improves stiffness and eliminates clearance during operation.
What lubrication method is recommended?
The XSU140644 can be lubricated with either grease or oil. For long-term, maintenance-friendly setups, grease lubrication is typically chosen. For high-speed or high-temperature environments, oil lubrication is preferred.
What industries benefit the most from using XSU140644?
This bearing is widely used in machine tools, robotics, aerospace, defense systems, precision measuring equipment, and heavy automation where long-term stability and high positioning accuracy are crucial.
