By adopting a multi-row roller, we have achieved high rigidity, high precision, and compactness.
By adopting a multi-row design for the rolling surface and using small-diameter rollers, the number of rollers has increased to about five times that of the conventional THK cross roller ring RU type (in the case of RW228). While maintaining compactness, rigidity and precision have improved, and torque reduction has also been achieved. Additionally, the inner and outer rings, which have a unified structure, are equipped with mounting holes, allowing for direct fixation to the equipment. ● Adoption of a unified structure for the inner and outer rings The inner and outer rings are designed as a unified structure, achieving high rigidity and high precision. ● Low torque By using small-diameter rollers, the friction coefficient is reduced, resulting in lower torque and lower temperature rise characteristics. ● Adoption of multi-row unidirectional rollers While maintaining almost the same dimensions as the conventional type, the number of raceway rows has doubled, enhancing rigidity.
