SLIDE WAY・GONIO WAY
GONIO WAY
This is a low friction resistance, non-circulation type curvilinear motion bearing with precision cross rollers. It is mainly used in optical and measuring instruments that require high precision.
Features
The NB Gonioway RVF type consists of a curved raceway with a precision ground V-groove and a flat mounting surface, and a curved roller cage with cross rollers. The NB Gonioway RV type consists of a curved roller cage with a precision ground V-groove. Precision rollers are used as rolling elements, and the non-circulating type provides low fluctuation of frictional resistance, resulting in extremely low frictional resistance curvilinear motion.
Low friction resistance micro feed
The precision grinding process and curved roller cage ensure extremely low frictional resistance and almost no difference between starting friction and dynamic friction, so that even minute feeds are accurately followed, resulting in high-precision curved motion.
Low noise
The gonioway is a non-circulating type, so there is no noise generation in the circulation section, and the curved roller cage eliminates contact noise between the rolling elements, resulting in quiet operation.
High rigidity and high load capacity
Rollers have a larger contact area than balls, resulting in less elastic deformation. Furthermore, because they are non-circulation type, they have a larger number of effective rolling elements, resulting in high rigidity and high load capacity.
Flat mounting surface
The RVF type has a flat surface for mounting, eliminating the need for difficult machining of the table or bed for assembly of this product, thus significantly reducing machining costs.
Identical center of rotation position
The RVF type has a curve transfer groove that is precision ground to obtain an accurate center of rotation. The RVF type is also configured so that the same center of rotation position can be obtained even when two axes of each size are combined.
