The XV30 Crossed Roller Bearing is a compact, high-rigidity rotary solution designed for advanced precision engineering. It features a unique split inner ring and an integrated outer ring equipped with 12 mounting holes, allowing for direct-bolt installation and exceptional rotational accuracy. By arranging cylindrical rollers in a 90-degree cross pattern, the XV30 handles radial, axial, and moment loads simultaneously in a remarkably slim 14mm profile.
Integrated Outer Ring: Features 12 precision mounting holes for stable, direct-bolt installation.
Split Inner Ring Design: Optimized for applications where high outer-ring rotation accuracy is required.
Compact High Rigidity: Delivers massive stiffness and load capacity within a narrow 14mm width.
Backlash-Free Motion: Crossed-roller geometry ensures smooth, play-free rotation for robotic joints.
Multi-Directional Support: Manages complex radial, axial, and tilting moment loads in one unit.

The split inner ring allows for precise adjustment of the internal clearance and preload during assembly, which is critical for achieving zero-backlash in high-precision robotic joints.
The integrated outer ring can be bolted directly to your equipment. However, the split inner ring should be secured with a clamping flange to maintain its structural integrity and preload setting.
The limiting speed is approximately 910 RPM with preload and can reach up to 1,800 RPM with standard clearance using grease lubrication.
