Double row angular contact ball bearing can be used to undertake greater axial load, mainly installed Double Row Angular Contact Ball Slewing Ring in the components for restricting the both sides of the bearing axial shell displacement．
By integrating double-row small-diameter rollers on the raceway, the number of rollers incorporated in this new model (RW228) is approximately 5 times that of Cross-Roller Ring model RU*. While maintaining the compactness, it achieves higher rigidity and accuracy and a lower torque. In addition, the inner and outer rings in integrated structures have mounting holes, allowing the product to be directly mounted to the machine.By integrating double-row small-diameter rollers on the raceway, the number of rollers incorporated in this new model (RW228) is approximately 5 times that of Cross-Roller Ring model RU*.
