Core Technologies and Unique Advantages of XRE Crossed Roller Bearings

The XRE series bearings utilize a unique crossed roller arrangement, with cylindrical rollers arranged in a 90-degree V-shape between the inner and outer rings, separated by spacers. This ingenious design offers the following unparalleled advantages:

Ultra-High Rigidity and Load Capacity: The unique line-of-contact design between the rollers and raceways enables a single bearing to simultaneously withstand loads in multiple directions, including radial, axial, and overturning moments. Its rigidity is several times greater than that of conventional bearings, effectively suppressing vibration-induced errors and ensuring stable and accurate equipment operation.

Ultimate Rotational Accuracy: Strictly controlled roller diameter and raceway tolerances, combined with precision manufacturing processes, ensure XRE bearings offer exceptionally high rotational accuracy, making them particularly suitable for precision applications requiring submicron positioning.

Compact Design, Space Savings: Compared to traditional combinations of two thrust bearings and one radial bearing, the XRE bearing's single-piece design significantly simplifies the structure, saving valuable installation space and simplifying the installation process, reducing the overall size and weight of the equipment.

Simplify Installation and Reduce Costs: The integrated design eliminates the need for complex preload adjustments and allows for simple bolt-on installation, significantly reducing assembly time and labor costs while also preventing precision loss due to improper installation.
