Ultra-High Rigidity and Load-Carrying Capacity: The XRC series bearings utilize a crossed roller arrangement, with cylindrical rollers alternately arranged at 90° angles to each other. This design allows a single bearing to simultaneously withstand multiple loads, including radial, axial, and tilting moments, while offering several times greater rigidity than conventional bearings. This is crucial for applications requiring extremely high stability and repeatable positioning accuracy.
Ultimate Rotational Accuracy: The linear contact between the rollers and raceways effectively reduces friction, ensuring ultra-high rotational accuracy and smooth operation. We offer a variety of precision grades, including P4 and P2, to meet your most demanding precision requirements.
Compact and Lightweight, Space-Saving: The XRC series bearings feature an integrated inner and outer ring design, resulting in a highly compact design. Compared to conventional bearings, this design significantly reduces installation space and weight, making it ideal for applications with strict size requirements.
Easy Installation and Low Maintenance: Thanks to its design, the XRC series bearings significantly simplify installation. The preload is set at the factory, requiring only simple installation and fixing, significantly reducing on-site commissioning and maintenance costs.
