RE Series Crossed Roller Bearings

RE Series Crossed Roller Bearings are a type of precision bearing designed for high rigidity, compactness, and the ability to handle complex loads in all directions. The RE Series features an integrated outer ring and a split inner ring, making it particularly suitable for applications that require high rotational accuracy and where the inner ring needs to be fixed with high rigidity. The RE Series has an integrated outer ring and a split inner ring. This configuration is designed to enhance rigidity and precision in applications where the inner ring is mounted directly onto a shaft or other rotating parts. The integrated outer ring ensures the bearing maintains its shape under load, while the split inner ring allows for slight adjustments during installation, which can improve the overall performance.
