Suitable for Minute Motion: The frictional resistance is extremely small and there is little or no difference between the static and dynamic frictional resistance. The NB Gonio slide way is well suited for minute motion. It can follow minute motion accurately, resulting in highly accurate curved motion. High Rigidity and High Load Capacity: The rollers provide a larger contact area than ball elements and there is less elastic deformation. Additionally, since the rollers do not recirculate, the effective number of rotating elements is larger, resulting in high rigidity and high load capacity. H-62 RV type The NB Gonio way is a curved SV type slide way. It is a curved motion bearing utilizing lowfriction, non-recirculating, precision cross-rollers. It is used when there is a need to change the gradient or obtain an accurate gradient angle without changing the center of rotation in high-precision optical and measurement equipment. STRUCTURE AND ADVANTAGES The NB Gonio way consists of hardened curved tracking bases with precisely machined V-grooves and a curved roller cage with cross-rollers. High-precision rollers are used as the rotating elements. Since the rotational elements do not recirculate, there is less friction fluctuation, resulting in a low-frictional curved motion. Figure H-42 Structure of RV Type Gonio Way end piece Ease of Assembly and Installation: The rollers are retained inside a curved roller cage, allowing assembly, installation, and the handling of components simplified. A set of components consists of 4 curved tracking bases, 2 curved roller cages, and 8 end pieces. It can be assembled immediately. Low Noise: The use of a roller cage prevents noise from being generated by contact between the rotating elements, resulting in quiet operation. rail curved roller cage
