How do I select the appropriate XRBC bearing for my equipment?

To select the right XRBC bearing, consider the inner diameter, outer diameter, and width based on your equipment design. Evaluate the radial and axial loads your equipment may experience and choose a bearing with the required load capacity. Additionally, select the appropriate preload to ensure optimal bearing rigidity and precision during operation. Our technical team can provide expert selection advice and support to ensure you find the best high-precision bearing for your application.

Why Choose XRBC Series Crossed Roller Bearings for Precision Applications?

The XRBC series crossed roller bearing is distinguished by its unique cross-shaped design, with cylindrical rollers arranged alternately between the inner and outer rings. This design enables the bearing to handle radial loads, axial loads, and overturning moments simultaneously, offering superior rigidity and precision over traditional two-bearing combinations. The compact design also conserves installation space and enhances the load-bearing capacity of the equipment.

These bearings are ideal for high-precision applications such as the joints of industrial robots, where minimal rotational misalignment is critical. The line contact between the rollers and raceways, along with their cross-shaped arrangement, allows XRBC bearings to withstand greater loads and resist overturning moments, ensuring stability under heavy loads or high speeds.

The XRBC series is not only limited to standard models but also supports customization, catering to a wide range of applications and specific performance requirements. This flexibility, combined with our commitment to quality and precision engineering, positions the XRBC series as a top choice for equipment that demands reliable and precise performance.
