Low friction resistance, non-recirculating type curved motion bearing using precision cross rollers.
The Gonioway "RV/RVF type" is mainly used in optical instruments and measuring devices that require high precision, such as when it is necessary to change the inclination without altering the position of the rotation center or when an accurate angle of inclination is needed. Precision rollers are used as rolling elements, and since it is a non-circulating type, there is little variation in friction resistance, allowing for extremely low friction resistance in curved motion.

basic information
**Main Features** ○ Low friction resistance and minimal feed → The friction resistance is extremely low due to precision grinding and curved roller cages. → There is almost no difference between static and dynamic friction, allowing for precise tracking even with minimal feed, achieving high-precision curved motion. ○ Low noise → As a non-circulating type, there is no noise generated from circulation parts. → The use of curved roller cages eliminates contact noise between rolling elements, resulting in quiet operation. ○ High rigidity and high load capacity → The contact area of rollers is larger than that of balls, resulting in less elastic deformation. → As a non-circulating type, it has a high number of effective rolling elements, providing high rigidity and high load capacity. ○ Flat mounting surface → The flat mounting surface eliminates the need for complex machining of tables or beds to incorporate this product. ○ Same rotation center position → The curved transfer groove is precision ground to achieve an accurate rotation center. → When combined with two axes of each size, it is structured to maintain the same rotation center position. ● For more details, please contact us or refer to the catalog.
