XRBC Series

What are XRBC Series Crossed Roller Bearings?

The XRBC series crossed roller bearing is a special type of roller bearing with cylindrical rollers arranged alternately between the inner and outer rings. This cross-shaped design allows a single bearing to simultaneously withstand radial loads, axial loads, and overturning moments. Compared to traditional two-bearing combinations, the XRBC series bearings not only save installation space but also significantly improve the overall rigidity, precision, and load-bearing capacity of the equipment.

Core Advantages of XRBC Bearings: Why They're the Best Choice?

Extreme Precision: The XRBC series bearings feature a large contact area and closely spaced rollers, enabling minimal rotational misalignment. Their high precision makes them particularly suitable for equipment requiring precisely controlled motion, such as the joints of industrial robots.

High Rigidity and Load Capacity: Due to the line contact between the rollers and raceways and their cross-shaped arrangement, XRBC bearings can withstand greater loads than traditional bearings while also resisting overturning moments, ensuring stability under heavy loads or high speeds.

Compact Design: Compared to solutions using two separate bearings, the XRBC series integrates the functions of two bearings into a single structure, significantly simplifying the design and reducing installation space and overall size, resulting in more compact and efficient equipment.

Easy Installation: XRBC crossed roller bearings typically utilize a one-piece construction, making installation simpler and faster, reducing installation errors, and improving assembly efficiency.

Wide Range of Applications: As a versatile bearing, the XRBC series is widely used in industrial robot joints, CNC machine tool rotary tables, medical equipment, semiconductor manufacturing equipment, and various precision reducers.

How to Choose the Right XRBC Series Crossed Roller Bearing?

Choosing the right XRBC bearing requires considering the following key parameters:

Size and Model: Select the appropriate inner diameter, outer diameter, and width based on your equipment design. We offer a variety of standard models and also support custom designs.

Precision Grade: Choose bearings with varying precisions, such as P5, P4, and P2, based on application requirements.

Load Capacity: Evaluate the radial and axial loads your equipment may experience and select bearings with the required load capacity.

Preload: Select the appropriate preload to ensure optimal bearing rigidity and precision during operation.
