XRU Series

The XRU series crossed roller bearing is a compact, high-rigidity precision bearing. Its characteristic feature is that the rollers are arranged crosswise on a V-shaped raceway and separated by spacers. This design allows a single bearing to simultaneously withstand radial loads, axial loads, and overturning moments, simplifying mechanical design and saving space. Compared with traditional bearing combinations, the XRU series crossed roller bearings offer higher rotational accuracy and rigidity, while also being easier to install.

Core Advantages of XRU Series Crossed Roller Bearings

High Precision and High Rigidity: The cross-arranged rollers effectively distribute loads, providing extremely high rotational accuracy and rigidity. This makes them excellent for applications requiring stable, precise motion, such as CNC machine tools and measuring instruments.

Compact Design, Space-Saving: The XRU series bearings feature exceptionally small inner and outer ring dimensions, integrating the functionality of a single bearing into a compact footprint. This is crucial for equipment requiring miniaturization and lightweighting, such as collaborative robots (Cobots) and semiconductor manufacturing equipment.

Easy Installation, Reduced Costs: Because a single bearing can simultaneously support multiple loads, complex bearing combinations are unnecessary. This not only simplifies the design but also significantly reduces installation time and labor costs.

Low Friction, Smooth Operation: The cross-roller design and precision manufacturing process ensure extremely low friction during operation, resulting in smooth, fluid rotation and extended equipment life.

High Load Capacity: The V-shaped raceway and cross-roller design provide a larger contact area, giving the XRU series bearings excellent load capacity and the ability to handle heavy and shock loads.

Typical Applications of XRU Series Crossed Roller Bearings

Due to their unique advantages, XRU series bearings are widely used in numerous fields:

Industrial Robots: In robot joints and harmonic reducers, XRU series bearings provide high-precision, high-rigidity support, ensuring accurate robot motion.

Precision Turntables: Whether it's a CNC machine tool turntable or a radar antenna turntable, XRU bearings ensure high-precision rotation and stable operation.

Semiconductor Equipment: In wafer transfer equipment and chip manufacturing equipment, which require extremely high precision, XRU series bearings are key components for ensuring production quality.

Medical Equipment: In medical equipment such as CT scanners and surgical robots, which demand the highest levels of precision and reliability, XRU series bearings provide reliable motion solutions.

How to Choose the Right XRU Series Crossed Roller Bearing?

When selecting an XRU series bearing, you need to consider the following key factors:
