Description

Double-Row Angular Contact Roller Rings

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.
